Computer-aided design (cad) produces better products but always increases the time to design them.

Product development and CAD software go hand-in-hand. In product development, CAD software is often used by engineers and designers to create blueprints of product designs. But what are the advantages and disadvantages of using CAD?

Advantages of using CAD for Product Development

Quicker Product Design Cycles

Product development is the process of bringing a new product to market. It encompasses everything from initial feasibility studies and market research to design, prototyping, and manufacturing. Traditionally, product development has been a time-consuming and expensive process, but the advent of computer-aided design (CAD) has made it possible to create new products in a fraction of the time and at a fraction of the cost.

CAD software enables designers to create virtual models of potential products and test them for form, fit, and function before a physical prototype is ever built. This not only saves money on prototyping costs but also allows for quicker design cycles, as new versions of the product can be generated and tested in a matter of hours or days rather than weeks or months.

Better Product Quality

Product quality is a key factor in product success. The better the quality of a product, the more satisfied customers are likely to be and the more likely they are to return for future purchases. CAD software helps designers create products that meet or exceed customer expectations for quality.

In addition, CAD software can help identify potential design flaws before they result in product failures. By identifying and correcting design problems early in the product development process, CAD software can help ensure that products are of the highest quality possible.

‍

Improved Customer Satisfaction Rates

According to a study by the Aberdeen Group, companies that use CAD software to design products have customer satisfaction rates that are 12% higher than companies that don’t use CAD. This is likely due to the fact that CAD-designed products are of higher quality and meet or exceed customer expectations for quality.

‍

Increased Production Efficiency

CAD software can also help manufacturers increase production efficiency. For example, product designs that have been created using CAD can be easily transferred to computer-aided manufacturing (CAM) systems, which can then be used to produce product prototypes or even the final product. In addition, CAD software can help manufacturers optimize product designs for manufacturability, which can lead to increased production efficiency and lower manufacturing costs.

‍

Lower Product Development Costs

Product development is a costly process, but the use of CAD software can help reduce those costs. The use of CAD software can help designers and engineers reduce the amount of time spent on product development, which in turn reduces the cost of bringing a product to market.

Disadvantages of CAD Software

The Need for Specialized Skills and Training

One downside to using CAD software is that it requires specialized skills and training. Unless you have a background in engineering or product design, it can be difficult to use CAD software effectively.

‍

The Potential for Product Design Errors

Another potential downside of using CAD software is the risk of product design errors. When designs are created using a computer, there is always the possibility that mistakes will be made. These mistakes can often be difficult to detect and can lead to product failures down the road.

‍

Can be Expensive to Purchase and Maintain

CAD software can be expensive to purchase and maintain. In addition, the hardware needed to run CAD software (e.g., a high-powered computer with a graphic card) can also be costly.

In conclusion, while CAD has some disadvantages, its advantages far outweigh them. CAD software can help designers create products that are of the highest quality, meet or exceed customer expectations, and are more efficient to produce. As a result, using CAD can lead to increased product sales and improved profitability for businesses.

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, yet with the introduction of CAD, technology’s role in the industry and the impact it has on the job have both grown.

History of CAD

The origins of CAD trace back to the early 60s and 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 nine in 10 of 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 a hit.

 Purpose of CAD 

Used by engineers, architects, and construction managers, CAD has replaced manual drafting. It helps users creating designs in either 2D or 3D so that they can visualize the construction.

CAD enables the development, modification, and optimization of the design process.

CAD enables the development, modification, and optimization of the design process. Thanks to CAD, 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 contractor and subcontractors. This way, it is possible for relevant parties to recognize the possible impact the changes might have on construction and adapt as needed. Such ready access to plans improves communication.

Effective utilization of all information ultimately increases productivity. CAD enables designers to consider electricity, plumbing, and other elements, helping to create a more comprehensive design. Ultimately, this translates to fewer work changes and fewer surprises during construction.

CAD and its spinoffs, with their many features, have become a staple throughout the construction industry and through all phases of the process. Its technological impact has been a game-changer in the industry—it has transformed construction into a technology job. 

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.

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

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 elevations of roads, bridges, etc. 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.”

There are many available CAD offerings that may be particularly helpful to those in construction. Below are some of the best-rated CAD software for the construction industry.

Best CAD Software Available

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 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 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.

The technology and its spinoffs have become a must-have for construction projects of all types and at all stages.

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, has powerful 3D design capabilities. Admittedly, it can be used to create 2D designs, but it is the 3D-related tools that 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.

CAD has come a long way since Hanratty, Sutherland, and others invented and improved it. The technology and its spinoffs have become a must-have for construction projects of all types and at all stages. It improves accuracy, heightens communication, speeds up the construction process, and reduces costs.
