The Enduring Significance of Technical Drawings in Engineering: From Blueprint to Innovation

In the dynamic realm of engineering, where cutting-edge technologies like Computer-Aided Design (CAD) dominate, the traditional art of technical drawing remains an indispensable pillar of the industry. While CAD has revolutionized drafting and design, technical drawings persist as a foundational element, playing a crucial role in communication, conceptualization, and precision across various engineering disciplines.

Understanding Technical Drawings: Technical drawings, synonymous with engineering drawings, are meticulous plans or diagrams that delineate the intricacies of a component’s functionality or construction. Serving as a reference for contractors, electricians, and engineers, these blueprints offer a detailed roadmap for constructing, renovating, or maintaining structures.

The Essence of Precision in Prototyping: The development of prototypes heavily relies on technical drawings, particularly in mass production scenarios. These drawings become the cornerstone of the manufacturing process, ensuring that the construction of objects proceeds seamlessly, devoid of errors, delays, or costly complications. Precision is the paramount duty of technical drawings, requiring them to be scaled, labelled, and organized with meticulous accuracy.

The Art of Standardization: What sets technical drawings apart is the degree of standardization they uphold. Unlike simple sketches, technical drawings provide a comprehensive view of an object, encompassing layout, line thickness, descriptive geometry, text size, symbols, and view projections. This precision leaves no room for misinterpretation, underscoring their significance in the overall design process.

Beyond 2D: The Cutaway Drawing: A counterpart to the traditional technical drawing is the cutaway drawing, which offers a translucent 3D depiction of the object. This hybrid approach allows engineers to visualize both external and internal details, providing a clearer understanding of the finished state.

The Crucial Role in Engineering: Communication & Coordination: Technical drawings serve as a universal language, facilitating communication and coordination between designers and producers in the realization of ideas. Engineers, builders, and architects can comprehend and implement designs seamlessly.

Conceptualizing: Acting as an instruction manual, technical drawings offer a precise visual representation of the intended product, eliminating ambiguity and ensuring a clear understanding of specifications. This visual language streamlines the manufacturing process.

Applications Across Engineering Disciplines: Technical drawings find application across various engineering disciplines, including architecture, electrical engineering, mechanical engineering, and civil engineering. Proficiency in technical drawing is indispensable in the manufacturing and Architecture, Engineering, and Construction (AEC) sectors, mitigating production delays and preventing the manufacture of defective components.

In an era of technological evolution, technical drawings persist as the bedrock of engineering innovation. Their enduring importance lies in their ability to transcend traditional drafting methods, providing a meticulous and standardized framework for communication, conceptualization, and precision in the dynamic field of engineering.

Great read, kudos on articulating the essence of technical drawings so eloquently!

Thank You:) From the get go our lecturers emphasise on the importance of drawing and how it is a language for engineers, so I though it would be a nice topic to share!

Where to Put Dimensions

Introduction

One of the best ways to communicate one’s ideas is through some form of picture or drawing. This is especially true for the engineer. The purpose of this guide is to give you the basics of engineering sketching and drawing.

We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings.

This is just an introduction. Don’t worry about understanding every detail right now - just get a general feel for the language of graphics.

We hope you like the object in Figure 1, because you’ll be seeing a lot of it. Before we get started on any technical drawings, let’s get a good look at this strange block from several angles.

Figure 1 - A Machined Block.

The representation of the object in figure 2 is called an isometric drawing. This is one of a family of three-dimensional views called pictorial drawings. In an isometric drawing, the object’s vertical lines are drawn vertically, and the horizontal lines in the width and depth planes are shown at 30 degrees to the horizontal. When drawn under these guidelines, the lines parallel to these three axes are at their true (scale) lengths. Lines that are not parallel to these axes will not be of their true length.

Figure 2 - An Isometric Drawing.

Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal. One can pack a great deal of information into an isometric drawing. However, if the object in figure 2 had a hole on the back side, it would not be visible using a single isometric drawing. In order to get a more complete view of the object, an orthographic projection may be used.

Orthographic or Multiview Drawing

Imagine that you have an object suspended by transparent threads inside a glass box, as in figure 3.

Figure 3 - The block suspended in a glass box.

Then draw the object on each of three faces as seen from that direction. Unfold the box (figure 4) and you have the three views. We call this an “orthographic” or “multiview” drawing.

Figure 4 - The creation of an orthographic multiview drawing.

Figure 5 - A multiview drawing and its explanation.

Which views should one choose for a multiview drawing? The views that reveal every detail about the object. Three views are not always necessary; we need only as many views as are required to describe the object fully. For example, some objects need only two views, while others need four. The circular object in figure 6 requires only two views.

Figure 6 - An object needing only two orthogonal views.

Figure 7 - An isometric view with dimensions.

We have “dimensioned” the object in the isometric drawing in figure 7. As a general guideline to dimensioning, try to think that you would make an object and dimension it in the most useful way. Put in exactly as many dimensions as are necessary for the craftsperson to make it -no more, no less. Do not put in redundant dimensions. Not only will these clutter the drawing, but if “tolerances” or accuracy levels have been included, the redundant dimensions often lead to conflicts when the tolerance allowances can be added in different ways.

Repeatedly measuring from one point to another will lead to inaccuracies. It is often better to measure from one end to various points. This gives the dimensions a reference standard. It is helpful to choose the placement of the dimension in the order in which a machinist would create the part. This convention may take some experience.

There are many times when the interior details of an object cannot be seen from the outside (figure 8).

Figure 8 - An isometric drawing that does not show all details.

We can get around this by pretending to cut the object on a plane and showing the “sectional view”. The sectional view is applicable to objects like engine blocks, where the interior details are intricate and would be very difficult to understand through the use of “hidden” lines (hidden lines are, by convention, dotted) on an orthographic or isometric drawing.

Imagine slicing the object in the middle (figure 9):

Figure 9 - “Sectioning” an object.

Figure 10 - Sectioning the object in figure 8.

Take away the front half (figure 10) and what you have is a full section view (figure 11).

Figure 11 - Sectioned isometric and orthogonal views.

The cross-section looks like figure 11 when it is viewed from straight ahead.

To prepare a drawing, one can use manual drafting instruments (figure 12) or computer-aided drafting or design, or CAD. The basic drawing standards and conventions are the same regardless of what design tool you use to make the drawings. In learning drafting, we will approach it from the perspective of manual drafting. If the drawing is made without either instruments or CAD, it is called a freehand sketch.

Figure 12 - Drawing Tools.

"Assembly" Drawings

An isometric view of an “assembled” pillow-block bearing system is shown in figure 13. It corresponds closely to what you actually see when viewing the object from a particular angle. We cannot tell what the inside of the part looks like from this view.

We can also show isometric views of the pillow-block being taken apart or “disassembled” (figure 14). This allows you to see the inner components of the bearing system. Isometric drawings can show overall arrangement clearly, but not the details and the dimensions.

Figure 13 - Pillow-block (Freehand sketch).

Figure 14 - Disassembled Pillow-block.

A cross-sectional view portrays a cut-away portion of the object and is another way to show hidden components in a device.

Imagine a plane that cuts vertically through the center of the pillow block as shown in figure 15. Then imagine removing the material from the front of this plane, as shown in figure 16.

Figure 15 - Pillow Block.

Figure 16 - Pillow Block.

This is how the remaining rear section would look. Diagonal lines (cross-hatches) show regions where materials have been cut by the cutting plane.

Figure 17 - Section “A-A”.

This cross-sectional view (section A-A, figure 17), one that is orthogonal to the viewing direction, shows the relationships of lengths and diameters better. These drawings are easier to make than isometric drawings. Seasoned engineers can interpret orthogonal drawings without needing an isometric drawing, but this takes a bit of practice.

The top “outside” view of the bearing is shown in figure 18. It is an orthogonal (perpendicular) projection. Notice the direction of the arrows for the “A-A” cutting plane.

Figure 18 - The top “outside” view of the bearing.

A half-section is a view of an object showing one-half of the view in section, as in figure 19 and 20.

Figure 19 - Full and sectioned isometric views.

Figure 20 - Front view and half section.

The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. These lines are called section lining or cross-hatching . The lines are thin and are usually drawn at a 45-degree angle to the major outline of the object. The spacing between lines should be uniform.

A second, rarer, use of cross-hatching is to indicate the material of the object. One form of cross-hatching may be used for cast iron, another for bronze, and so forth. More usually, the type of material is indicated elsewhere on the drawing, making the use of different types of cross-hatching unnecessary.

Figure 21 - Half section without hidden lines.

Usually hidden (dotted) lines are not used on the cross-section unless they are needed for dimensioning purposes. Also, some hidden lines on the non-sectioned part of the drawings are not needed (figure 12) since they become redundant information and may clutter the drawing.

Sectioning Objects with Holes, Ribs, Etc.

The cross-section on the right of figure 22 is technically correct. However, the convention in a drawing is to show the view on the left as the preferred method for sectioning this type of object.

Figure 22 - Cross section.

The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines.

• Accuracy: correct values must be given.
• Clearness: dimensions must be placed in appropriate positions.
• Completeness: nothing must be left out, and nothing duplicated.
• Readability: the appropriate line quality must be used for legibility.

The Basics: Definitions and Dimensions

The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (figure 23).

Figure 23 - Dimensioned Drawing.

An arrowhead is approximately 3 mm long and 1 mm wide. That is, the length is roughly three times the width. An extension line extends a line on the object to the dimension line. The first dimension line should be approximately 12 mm (0.6 in) from the object. Extension lines begin 1.5 mm from the object and extend 3 mm from the last dimension line.

A leader is a thin line used to connect a dimension with a particular area (figure 24).

Figure 24 - Example drawing with a leader.

A leader may also be used to indicate a note or comment about a specific area. When there is limited space, a heavy black dot may be substituted for the arrows, as in figure 23. Also in this drawing, two holes are identical, allowing the “2x” notation to be used and the dimension to point to only one of the circles.

Where To Put Dimensions

The dimensions should be placed on the face that describes the feature most clearly. Examples of appropriate and inappropriate placing of dimensions are shown in figure 25.

Figure 25 - Example of appropriate and inappropriate dimensioning.

In order to get the feel of what dimensioning is all about, we can start with a simple rectangular block. With this simple object, only three dimensions are needed to describe it completely (figure 26). There is little choice on where to put its dimensions.

Figure 26 - Simple Object.

We have to make some choices when we dimension a block with a notch or cutout (figure 27). It is usually best to dimension from a common line or surface. This can be called the datum line of surface. This eliminates the addition of measurement or machining inaccuracies that would come from “chain” or “series” dimensioning. Notice how the dimensions originate on the datum surfaces. We chose one datum surface in figure 27, and another in figure 28. As long as we are consistent, it makes no difference. (We are just showing the top view).

Figure 27 - Surface datum example.

Figure 28 - Surface datum example.

In figure 29 we have shown a hole that we have chosen to dimension on the left side of the object. The Ø stands for “diameter”.

Figure 29 - Exampled of a dimensioned hole.

When the left side of the block is “radiuses” as in figure 30, we break our rule that we should not duplicate dimensions. The total length is known because the radius of the curve on the left side is given. Then, for clarity, we add the overall length of 60 and we note that it is a reference (REF) dimension. This means that it is not really required.

Figure 30 - Example of a directly dimensioned hole.

Somewhere on the paper, usually the bottom, there should be placed information on what measuring system is being used (e.g. inches and millimeters) and also the scale of the drawing.

Figure 31 - Example of a directly dimensioned hole.

This drawing is symmetric about the horizontal centerline. Centerlines (chain-dotted) are used for symmetric objects, and also for the center of circles and holes. We can dimension directly to the centerline, as in figure 31. In some cases this method can be clearer than just dimensioning between surfaces.

Section 2: Tools and Equipment for Engineering Drawing

Engineering drawing has been an integral part of design and manufacturing for centuries, and over time, the tools used in this field have evolved dramatically. From the traditional drawing instruments that were once the cornerstone of the industry to the modern software applications that have revolutionized the way we work, engineering drawing tools are as diverse as they are essential. In this section, we’ll explore both the traditional and modern tools used in engineering drawing and compare their features and applications.

Before the age of computers, engineering drawings were crafted manually using a variety of specialized tools:

• – Pencils: Various grades of pencils were used for different line types and thicknesses.
• – Compasses: Essential for drawing arcs and circles with precision.
• – Protractors: Used to measure and draw specific angles.
• – Rulers and Scales: For creating straight lines and measuring distances accurately.
• – Drafting Boards: Provided a stable surface with adjustable angles for drawing.
• – Templates: Containing common shapes and symbols for consistency.

These traditional tools required a skilled hand and a keen eye for detail, laying the foundation for the principles still used in modern engineering drawing.

The introduction of computer-aided design (CAD) software has brought a new era of efficiency and precision to engineering drawing:

• – AutoCAD: A versatile tool used across various disciplines for 2D and 3D modeling.

• – Preservation: Digital drawings can be stored and retrieved easily, minimizing the risk of damage or loss.

However, learning traditional methods still holds value, as it instills a deep understanding of geometric principles, spatial thinking, and attention to detail.

Section 3: Basic Principles of Engineering Drawing

Engineering drawing is more than just sketching lines and shapes; it’s a disciplined practice that adheres to well-defined principles and standards. These foundational concepts ensure that the drawings are accurate, consistent, and universally understood. In this section, we’ll explore the basic principles that govern engineering drawing, including geometric shapes, lines, angles, dimensions, scale, proportion, symbols, and notations.

Geometry is the backbone of engineering drawing, providing the building blocks for complex designs:

• – Circles and Arcs: Used to represent curves, bearings, and rounded components.
• – Triangles: Often employed to symbolize structural elements or to create specific angles.
• – Rectangles and Squares: Commonly used for regular parts, enclosures, and frames.
• – Polygons: Versatile shapes that can represent gears, bolts, and other mechanical components.

Understanding the properties and applications of these basic shapes is essential for creating accurate and functional drawings.

The use of lines, angles, and dimensions in engineering drawing serves specific purposes:

• – Lines: Different types of lines (continuous, dashed, dotted) indicate visible edges, hidden features, centerlines, etc.
• – Angles: Precise measurement of angles ensures proper alignment and orientation of components.
• – Dimensions: Clearly labeled dimensions (length, width, diameter) provide the measurements necessary for fabrication.

These elements form the visual language that conveys the exact specifications of a design.

Scale and proportion are vital in representing objects accurately:

• – Scale: The ratio between the size of the drawing and the actual object. It allows for large objects to be drawn on a manageable scale or small objects to be magnified for detail.
• – Proportion: Maintaining the correct relationships between different parts of the drawing, ensuring that all elements are in harmony with each other.

Choosing the right scale and maintaining proportion ensures that the drawing faithfully represents the real-world object.

Engineering drawing employs a standardized set of symbols and notations:

• – Symbols: Icons and figures that represent common features like welds, tolerances, finishes, etc.
• – Notations: Alphanumeric characters used for labeling, numbering, and adding notes to the drawing.

These symbols and notations enable quick communication of complex information, and their standardized use ensures that the drawing is universally understood.

Section 4: Techniques and Methods

Creating an engineering drawing is a systematic process that requires careful planning, execution, and attention to detail. While the principles set the foundation, the techniques and methods bring those concepts to life, translating ideas into tangible drawings. In this section, we’ll explore a step-by-step guide to creating an engineering drawing, offer tips for sketching, dimensioning, and detailing, and discuss common mistakes and how to avoid them.

• **Understand the Requirements** : Analyze the specifications, constraints, and purpose of the drawing.
• **Choose the Right Tools** : Select appropriate software or traditional tools based on the complexity and needs of the drawing.

Extract of sample "Engineering drawing"

Drawing is considered as a vital part of the entire engineering assignment and is a major portion of the designing region of the field of engineering. There are several fields of engineering, including: mechanical, technical and civil engineering and all fields have placed certain amount of importance on the activity of engineering drawing. Engineering drawing has two meanings, firstly it is the act of drawing itself and secondly it is the output of drawing or a piece of art that is visible to others.

Engineering drawing is considered as a language and this language even comprises of grammatical rules such as the grammatical rules invested in English language (Ve?n?ugo?pa?l V). There is a huge difference between both engineering drawing and artistic drawing although certain amount of people may use both the terms interchangeably. All engineers need to learn the proper way of conducting the act of engineering drawing as it can have devastating effects as any language if not used in the proper manner can have devastating impacts.

Body Those who are not related to the field of engineering may regard both engineering as well as artistic drawing as simply drawing; both engineers and artists may share similar traits as both are involved in the process of drawing images. But the purpose of both types of drawings differ, drawing that is artistic in nature is conducted with the purpose of conveying emotional messages, and the purpose of engineer made drawing is to spread information and provide insight (Madsen 11). Another major difference between both forms of drawing is that of understanding, in order to understand engineer made drawings, one needs to have knowledge of the field of engineering.

The engineer has to pass through a particular possess and needs to obtain certain skill set in order to develop drawings for engineering purpose. This process is even regarded as technical drawing and is used in various disciplines of engineering and non engineering disciplines. Engineering is a very vast field and they may share certain common types of drawings and certain drawings are only limited to a particular field of engineering. For example in the case of metal engineering, the field specific types of drawings may include fabrication and casting and the fabrication part of metal engineering may further be divided into other forms of drawings.

Engineer made drawings even act as legal documentation as this document interacts and transfers information regarding what resources and assistance is desirable for those will ultimately transform a drawing of an idea into a real end product (Choi 10). Engineering drawings are used as a means of creating a contract between two parties, there are parties involved when an engineering idea in drawing form is sold to someone, it even becomes a part of the purchasers and sellers purchase and sale order and is even a part of any changes made to the product.

This drawing helps in saving a manufacturer from being held responsible if the manager had followed all the steps that were stated in the drawing and still failed to produce a successful outcome. In this scenario the drawing is analyzed and the engineer who drew the engineering drawing

The Importance of Engineering Drawing

Filed Under: Essays Tagged With: engineering

industrial engineering is a branch of engineering dealing with the optimization of complex processes or systems. It is concerned with the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, materials, analysis and synthesis, as well as the mathematical, physical and social sciences together with the principles and methods of engineering design to specify, predict, and evaluate the results to be obtained from such systems or processes [1] Basically, the science of Industrial Engineering can be divided into three areas of curriculum:

1. Basic science Including basic materials that related with basic technical science like mathematics and physics. 2. Engineering design Consist of engineering drawing, design process, electronic, etc. 3. Engineering science Divided into two classifications : a. Non industrial technical Like knowledge of materials, engineering mechanics, thermodynamics, etc. b. Industrial technical Like operation research, industrial statistic, industry dynamics, planning and control of industrial, etc. Picture is one way to declare intention of a person. As we know, sometimes there are some differences in understanding of a product.

The Essay on Industrial Engineering Engineers Materials Design

Industrial Engineering Industrial Engineering is concerned with the design, improvement, and installation of integrated systems of people, materials, equipment, information, and energy in the most efficient manner possible. ... in the mathematical, physical, and social sciences together with the principles and methods of engineering analysis and design to specify, predict and evaluate ...

To avoid that, we need a picture. The function of picture is in order to make the same understanding of a product for each person. Therefore, we need to learn engineering drawing. Engineering drawing allows efficient communication about a product since it communicates all needed information from the engineer who designed to the workers who will make it. What the importance of engineering drawing for Industrial engineering? As we have knew, before we produce our products, we need to design the shape of products, the shape and model of their wrapper products, the symbols, and many others related to the designing of their products [2].

To design them, we need to know and learn engineering drawing. Engineering drawing is one of the subjects that can support them who are studying in the Industrial Engineering. The main purpose of the engineering drawing in the industrial engineering is to give the ability and to develop the skill in reading and drawing the component of the machine and a product of manufacturing activity. Without the designing, no products that can be produced base on our planning or it can be different with our wish [3]. Even more, we cannot produce a thing if we do not have any designs of shape, size, and the format of it.

Moreover, the most important thing in studying engineering drawing is how we can imagine the shape of the real things in the picture [4]. Not only the shape of the real things, but also the size, and the way to create them must be analyzed by using engineering drawing [5]. Picture 1. Assembly of fan There are many steps that engineer must doing for completing a design, includes : information gathering, idea generation, concept enhancement and design visualization. Information gathering is the first step before engineers do their design. The main purpose of information gathering is to determine the information requirements of a product.

Engineers gathering the data and information from many sources, such as books, internet, journal, etc. For the example, if we want to make a fan, the first step we must do is collecting data and information about the components of the fan. The key components of fan are electrical motor, blades, flywheel, rotor, downrod, mounting bracket and decorative housing. After we do information gathering, we move to the second step, generate idea. In this step, we explore the idea through the hand-writing sketch and also the comprehension to the projection.

The Essay on Producing product within quality standards at least cost

Manufacturing sub-processes are part of the complete process in order to produce the needed goods in production. As VP for operations, part of the responsibilities is to make it sure that the products demanded by the market as articulated by the marketing department are used.  Basically, the for VP operation should be concerned with the production of goods and processed using the necessary ...

We are required to be able to point out our idea into the sketch. Based on the example, in this step, we need to point out our idea how the model of the fan that we want to make on sketch. This sketch has an important role to the next step because if we can not create our idea into the first sketch, we can’t gain the real design of fan which will be produced. The third step, concept enhancement is emphasize how this design picture or design product can fill the standards set, either national standards or international standards.

There are so many kind of standard code for example DIN, ANSI, JIS, AS, BS, but for the international standard we use ISO (International Standards Organization).

Even though concept enhancement should be done using tools directly, we must studying and knowing about national and international standard using. For the example in this case, we must know how to make a fan with international standard such as from the speed of the propeller, the number of blades that be used and etc. And the last process in engineering drawing is design visualization.

In this process we have to make design drawing fit to the situation of the real product. Because the design of the product will be useless if the design is not created into the real and tangible thing. In this step, high skill is needed. Visualization design should be carried out using modern tools, like computers. That’s because sometimes in visualization design we make some mistakes. So, by using modern tools we can reduce our costs and save our time. Computer has many software to design drawing. For example AutoCAD, Adobe Photoshop CS 3, Light Zone 1. , Corel Paint Shop Pro Photo, Adobe Photoshop Element, Ulead Photolmpact, Pain Buster, PhotoPlus, The GIMP, Magic Phot Clinic, Picasa, Photobie.

From 4 steps above, we can conclude that engineering drawing has important role in the industrial engineering as a way to communicate products between everyone in purpose or between companies either national or international. Because by engineering drawing, we can make a product become communicative, affective and accurate. Also, with engineering drawing, we have facilitate to make a new idea, a new creativity and improvement product or anything.

Computer-Aided Design (CAD): What It Is — and Why It’s Important

Last Updated Nov 16, 2023

When most people envision a construction worker, they see a person at a construction site wearing a hard hat and a safety vest. Perhaps this person is putting up drywall, hammering nails, laying flooring, or even having lunch high above the ground, evoking the iconic Lunch Atop a Skyscraper photograph . Although all these constitute part of the job, construction is in many ways a tech job . This has always been the case — but with the introduction of computer-aided design (CAD), technology’s role in the industry and the impact it has on the job have both grown .

Table of contents

History of CAD

The origins of CAD trace back to the early 1960s systems of Patrick Hanratty and Ivan Sutherland. While working for General Electric, Hanratty developed a program he called DAC , the first system which used interactive graphics and a numerical control programming system. 

Just two years later, in 1963, Ivan Sutherland designed a system that “broke new ground in 3D computer modeling and visual simulation, which is the basis for CAD.” Sutherland called his program Sketchpad, and explained it  “let designers use a light pen to create engineering drawings directly on a CRT.”

In 1971, Hanratty developed a program called ADAM . It was described as the “first commercially available integrated, interactive graphics design, drafting, and manufacturing system." Approximately 9 out of 10 CAD programs find their roots in ADAM.

Hanratty upgraded ADAM over time, enabling it to run on 16-bit, and later 32-bit computers. With a name change to AD-2000 along with more machining and surfacing capabilities, the program became more and more of a success.

Purpose of CAD 

Used by engineers, architects, and construction managers , CAD has replaced manual drafting in many places. It helps users create designs both 2D and 3D designs to better visualize construction.

CAD enables the development, modification, and optimization of the design process. Engineers can make more accurate representations and modify them easily to improve design quality. The software also takes into account how various materials interact: This is especially relevant as more details are added to drawings by subcontractors.   

Today, drawings/plans can be stored in the cloud, Thus, contractors have gained access to CAD-based drawings/plans at the worksite. Entire teams can check out plan modifications easily, including the general contractor and subcontractors. This way, it is possible for all the relevant parties to recognize the possible impact the changes might have on construction and adapt and communicate as needed.

Effective utilization of all information can help increase productivity . CAD helps enable designers to consider electricity, plumbing, and other elements to create a more comprehensive design. Ultimately, this translates to fewer work changes and fewer surprises during construction.

CAD in practice

Eric Cylwik is a senior virtual construction engineer at Sundt Construction, a full-service general contractor that is one of the largest construction companies in the United States. 

Cylwik focuses on virtual construction and has concentrated on 3D modeling for construction uses throughout his career. In his role at Sundt Construction, he supports the people in the construction business by identifying how technology can bring predictability, speed, and quality to their work. He also ensures the technology is working correctly.

Cylwik’s use of CAD dates back to his college days at Arizona State University where he majored in design studies. “It was the first tool I used when setting about creating 3D sequences and animation,” he said.

Today Cylwik regularly uses “a host of different CAD-related tools.” With their help, he can develop accurate models of something yet to be designed. He works out ways to transfer files among key players and create a final design intent model.  

“Being able to visualize something in 3D gives the design and construction team an idea of what the finished project should look like,” said Cylwik.

When Cylwik was in Sundt’s transportation group, he used CAD data to determine the elevations of roads, bridges, and other surfaces. The team connected CAD to equipment in the field to ensure the equipment was performing tasks according to the specs.

“Traditionally, this was labor-intensive but this [CAD] totally changes the process. It’s a time-saver; it improves safety and reduces costs.”

Popular CAD software options in construction

Cad civil 3d.

CAD Civil 3D is used for planning, designing, and managing civil engineering projects. The projects can be divided into “three main categories of land development, water, and transportation projects; and can include construction area development, road engineering, river development, port construction, canals, dams, embankments, and many others. … [It’s] used to create three-dimensional (3D) models of land, water, or transportation features while maintaining dynamic relationships to source data such as grading objects, breaklines, contours, and corridors.”

CAD Plant 3D

CAD Plant 3D makes offers modern 3D design solutions for plant designers and engineers. The program helps simplify the modeling of plant components, including piping and support structures. The software offers a number of tools to deal with typical plant and process design challenges, such as the standardization and customization of parts for a particular project. It also improves accuracy as well as increases design and engineering productivity as typical challenges are addressed when building the model. 

CATIA is a cloud-based design software used for physical modeling and is utilized in many industries. In construction, it facilitates the design of buildings. The software is also seen as a top-notch surfacing (developing the shape of an object) tool. What’s more, CATIA supports multiple stages of product design and aids in the design of various systems, such as electronic HVAC.

SkyCiv Structural 3D

SkyCiv Structural 3D is a cloud-based structural engineering software program geared toward civil and structural engineers. Completely online, the program enables users to model, analyze, and design a wide range of structures. Engineers can analyze multiple issues like bending, stress, and buckling. With smart repair model functionality, the program helps users identify and repair issues.

SolidWorks Premium

A program that runs on Microsoft Windows, SolidWorks Premium has powerful 3D design capabilities. While it can be used to create 2D designs, the 3D-related tools are what make it so valuable for mechanical engineers and designers. SolidWorks “integrates powerful design tools — including industry-leading part, assembly, and drawing capabilities with built-in simulation, rendering, animation, product data management, and cost estimation.” The program allows users to create a 3D model from a 2D plane, and vice versa.

Can Creating Art Make You a More Effective Engineer?

March/April 2019

BY STUART G. WALESH, PH.D., P.E., F.NSPE

Stronger visual abilities can help us be more effective and innovative, work and live smarter. Experience reveals that those of us who practice, as amateurs or professionally, one of the visual arts (such as drawing, painting, sculpture, or photography) develop enhanced observational capabilities. We see what others don’t. Accordingly, we literally and metaphorically define more thoroughly issues, problems, and opportunities, and we generate more innovative resolutions of them. In Seeing With the Mind’s Eye: The History, Techniques, and Uses of Visualization , the authors write, “Learning to see directly affects the ability to visualize. In seeing, the images are external; in visualizing, the images are internal.”

Many engineers will be more effective, especially more innovative and communicative, if they engage in a visual art—not just study one. My experience and research suggest that art’s professional and personal value emanates from actively doing it. Incidentally, I suspect that some of what I share is applicable to the performing arts as well.

More seeing and, relatively speaking, less just looking, is an inevitable by-product of practicing visual arts. Really seeing gradually becomes habitual for artists. When looking at anything, artists, relative to others, tend to see composition, shapes, colors, values, and details. As noted by Ralph Waldo Emerson, “The mind, once stretched by a new idea, never returns to its original dimensions.” And so it is once we engage in visual arts.

Drawing on the History of Drawing

To put visual arts in perspective, consider the evolution of one visual art form: pencil drawing, starting with the freehand version. Drawing, which means converting “a mental image into a visually-recognizable form,” was first employed at least four millennia ago by the predecessors of what are now scientists, engineers, architects, and other similar technical professionals.

Beginning about 1820, US engineers and other technical personnel started to learn projection or mechanical drawing, based on the French system first developed by Gaspard Monge. This systematic manual, but not freehand, form of drawing used tools like straight edges, triangles, and circle guides.

Near the end of the last century, the drawing component of engineering changed drastically, in that computerized graphic tools gradually eclipsed systematic manual drawing. Computer-aided graphics replaced graphite graphics. Therefore, today US engineering and scientific/technical education rarely includes manual drawing, and it is rare in practice.

Advances in drawing, from freehand to the more disciplined projection drawing and into today’s computerized drawing, have been largely beneficial, mainly because they increased the efficiency of drawing and the use of drawings.

However, these changes have had the negative effect of removing some right-brain stimulus potential from engineering education and, as a result, from practice. While computer-aided design and drafting tools are more sophisticated than freehand drawing, they share one characteristic—they are primarily left-brained.

In contrast, “freehand drawing, being free of technical symbols, is dominated by the right hemisphere of the brain,” explains the 1986 book Engineering: An Introduction to a Creative Profession . Further elaborated in the 2009 Successful Education: How to Educate Creative Engineers , “The spontaneity of freehand design, rather than being superfluous, permitted direct expression by parts of the brain that are not engaged by computer-aided drafting tools.”

As visual thinking consultant Dan Roam puts it, “Computers make it easy to draw the wrong thing.” Computer-aided drawing tools might also tempt us to draw the same old things or stop too soon in our creative-innovative efforts. “Technically-perfect, computer-generated drawings always seem to be complete and imply that the work is over,” notes Successful Education . These technically-perfect drawings limit a student’s or practitioner’s creativity and innovation because of the “limited number of objects available in a given computer tool.”

This historic sketch, while recognizing the advantages of computer-aided drawing, suggests that we should also recognize the disadvantages of over- or sole reliance on it. Why? Because freehand drawing, when used in series or parallel with computer-aided drawing, offers engineers, scientists, and other professionals significant benefits.

Enhancing Our Effectiveness As Engineers and Artists

What does enhanced seeing, derived from freehand drawing and other visual arts, have to do with professional work? Improved seeing, whether literally or figuratively, further enables us to define more completely and accurately an issue to be resolved, a problem to be solved, or an opportunity to be pursued. To paraphrase and expand the expression “a problem well defined is half solved,” a challenge more completely and accurately seen, both physically and figuratively, is half resolved, solved, or pursued. We are likely to gain valuable enhanced literal and metaphorical diagnostic vision because of participating in freehand drawing or other visual arts. That enhanced seeing will also enable us to more thoroughly and creatively visualize solutions to the challenges we face.

Learn from the work and words of some engineer-artists:

As a teenager, Leonardo da Vinci spent time in Florence, where he learned about and aspired to become one of the “ingenios,” the engineer/artists. Later, da Vinci, now the engineer-artist-scientist, dissected more than 30 human cadavers and many animal corpses. He conducted the first documented autopsy, in effect making da Vinci pathology’s founder.

Because da Vinci saw , and could draw, now others could see what they had not seen . He said there are three classes of people: “those who see, those who see when they are shown, those who do not see,” which supports the idea that doing art can enhance the sight of those who want to see more.

The architectural and engineering firm headed by Santiago Calatrava, the famous Spanish-born engineer and architect, designs creative, now-signature structures. Examples include a gently twisted Malmö, Sweden, skyscraper influenced by the human spine; a portion of the Milwaukee, Wisconsin, art museum with wings that open to the sky to moderate interior illumination; and the Lisbon, Portugal, train station inspired by a palm tree forest.

Calatrava earned a degree in architecture and a doctorate in civil engineering. He has held engineering licenses in the US, such as in Texas and Wisconsin. Calatrava draws, paints, sculpts, and does ceramics. He synthesizes some of his interests with this thought: “I have tried to get close to the frontier between architecture and sculpture and to understand architecture as an art.” And maybe we could replace “architecture” with “engineering,” or add “architecture” to “engineering” based on Calatrava’s engineering-architecture masterpieces. As a Smithsonian article noted, “Being an engineer frees him to make his architecture daring.”

Artist Wendy Crone is a professor in the Department of Engineering Physics at the University of Wisconsin – Madison where she also has appointments in the departments of Biomedical Engineering and Materials Science and Engineering. Crone’s research specialty is solid mechanics, which has connected her to nanotechnology and biotechnology. She does sculpting and pottery and paints with pastels.

In her research, Crone uses microscopy—that is, instrumentation that provides images of objects not visible to the naked eye. She says, “The ability to see detail and attend to subtle changes in images is critical to my engineering research,” and she believes that “these skills are enhanced by my practice of painting.”

As a teacher, Crone uses her art knowledge and skill to prepare visuals that enable students to understand complex concepts. Her art also supports collaboration with professional artists and scientists in preparing presentations, writing articles and papers, and designing museum exhibits.

Stephen Ressler, P.E., professor emeritus for the US Military Academy, works in oil, watercolor, pencil, and pen and ink. He creates mostly landscapes and architectural images.

He says, “doing art has been immensely influential in my development as an engineer and, especially, as an engineering educator.” Ressler describes the benefits of being an engineer-artist as dual-directional.

Doing art helps him be a more effective engineer because now he is more able to develop two-dimensional representations of three-dimensional objects; see details he might otherwise have missed; use sketches to communicate, particularly in design, and on a chalk-board when teaching; compose presentations; and develop three-dimensional computer models.

And doing engineering has made him a more effective artist because he can see and represent three-dimensional objects in two dimensions, see and represent detail, and master perspective drawing methods.

Like some of the preceding, I am an amateur artist working in pencil and acrylic and prefer realism such as landscapes and animals. A decade ago, after a five-decade lapse, I took a one-day freehand pencil drawing course, and enjoyed it. Classes and drawing continued, initially as a diversion but also because I gradually saw intriguing connections between doing art and doing engineering.

Some of my now-learned insights are identical to those already shared, in that, broadly stated, doing engineering enables me to do art, and doing art enables me to be a more effective engineer.

Consider a few more examples of the latter:

The accomplished artist applies rules of composition to draw us in, set a mood, and send a message. We are not sure why, but the human brain tends to respond favorably to classical composition rules traced back to at least the Renaissance. Many of those art rules also rule effective communication by engineers. For example, when designing an image, such as for a slide, put the focus point or principal image off-center, not in the center, though the latter would be a natural tendency.

And the odd-over-even composition rule, when applied to written or visual engineering communication, means favoring an odd number of major points, objects, conclusions, or recommendations.

Too many presentation slides use the format of a statement followed by several to many lines of text, each preceded by a bullet. In light of vision being the most powerful sense and recognizing composition rules, such as create a focus point and use an odd number, why do we make bland, all-text slides? Experience, art, and research indicate that the most effective slides, as determined by audience understanding and remembering, contain a declarative statement and a supporting image.

Benefits and Joys

Because vision dominates our senses, enhanced visual abilities enable engineers to be more effective. By doing—not just studying—one of the visual arts, such as drawing, painting, sculpture, or photography, we develop enhanced observational capabilities. We see what others don’t. Therefore, we more thoroughly define issues, problems, and opportunities and we more creatively resolve them.

Doing art enhances the development and ability of engineers. We see more details; more effectively represent three-dimensional objects with two-dimensional images; compose more-communicative text and images for presentations, published articles, and papers; and produce more creative processes, products, structures, facilities, and systems.

The engineer-art connection also works in the opposite direction. Engaging in engineering equips us to create enjoyable and productive art. Because we readily “see” in three dimensions, we can represent an object in two dimensions, and we understand principles of perspective drawing.

However, please recognize that just as we do some of our engineering for the fun of it, artists do some of their art for pleasure. For me, hours fly by as I enjoyably create images with pencils and paint. If you are not engaging in visual arts, consider exploring it. You may find a new joy—and enhanced engineering capability.
