A designer begins sketching the interior layout for a three-storey apartment. An engineer sits down to construct new automotive parts for a motorcycle. An architect starts drawing the city's next shopping mall floor plan for a construction project.
These are just some examples of what professionals across industries are doing.
The one thing they have in common? The use of Computer-Aided Design (CAD). These professionals use CAD software programs in one way or another as part of their design process to accomplish their tasks.
CAD software has allowed 2D & 3D models to be done much more efficiently, which leads to faster production of objects and products, and has created a new demand for professionals that are trained in using CAD software.
Read on to find out everything you need to know about CAD and why 2D & 3D models are important.
Computer-Aided Design and Drafting (CADD) is the use of computers to design physical components or outline processes. As the software offers detailed and precise instructions on how things should be made, it plays a significant role in numerous sectors, including the architecture, design, and engineering industries.
As its name suggests, CADD is similar to CAD software that allows for the drafting of an object. At times, both terms are used interchangeably.
Before CAD software was invented, professionals would have to draw on a rough layout with just a pencil to visualise the design they had in mind for manual drafting. This made it a hassle for professionals to make changes and redraw parts.
The invention of CAD allowed for the creation of 2D and 3D models that helped professionals visualise their designs better and present them easily, all at a lower cost. As technology's role in various industries grows, so has the demand for professionals trained in CAD.
CAD software allows professionals to work faster and complete projects more effectively. By digitising the designing processes, repetitive and troublesome tasks such as sketching and erasing drawings are eliminated. This reduces the time spent designing by a few days or weeks and accelerates production.
Reducing design errors is one of the most significant advantages CAD software can offer. With manual design, human errors are common and usually arise during the drafting process of a product. These risks are almost entirely eliminated by CAD software since it doesn't require any manual input during the design phase.
With CAD software, designs and notes can be stored digitally, which allows anyone in the team to refer to the drawing board for inspiration or in case of errors. In addition, having the ability to save designs lets the user revert and address any mistakes made, and enables designers to make any modifications to prevent mistakes before they occur.
Modifying designs in 2D models is easy. Unlike the conventional models where designs are created on paper, it only takes a couple of clicks to switch up a layout on a digital surface. As a result, a designer can create a realistic reproduction of the finished product and easily present how the selected elements work together in a defined space.
Although 3D CAD software offers its users numerous functions, few are often used for creating drawings. On the other hand, 2D CAD tools usually contain only the essential functions and are easy to use and understand. This enables designers to create drawings that work without unnecessary details.
2D CAD has minimum room for errors. Without the inherent details that 3D models bring, designers can digitally create components for products with precise dimensions confidently, as the CAD software can calculate the factors and changes made automatically. In turn, designers get accurate and faster iterations of their designers with little to no manual inputs.
3D modelling provides designers with the exceptional ability to make precise adjustments to their designs. 3D modelling allows every professional, no matter their industry, to tweak any aspect of a 3D product according to their preference without breaking a sweat.
While businesses from various industries are still adopting CAD software, making the most of 3D models for your company can place you a step further ahead of your competitors.
When applied correctly, 3D models used for presentations or shown in videos or images on your website can bring something more innovative and futuristic that helps you stand out to your customers among your competitors.
3D models allow for collaboration among engineers, designers and even others who are invested in the product but belong to neither of these groups. Regardless of their expertise, every team member can communicate with one another with the 3D model as their common reference point.
3D models allow for something that wasn't possible in the past, the ability for everyone and anyone to work on them without changing to a different software.
Architecture is well-known as one of the most demanding fields in terms of design. Given the level of detail required in modern construction, it's no wonder CAD software is often used in this field.
Architects use the software to create and produce technical drawings of buildings containing details and specifications that would be used in construction projects when constructing the final design of the building.
CAD software is not always used for the designing part of the product. Graphic designers often use them to add a little flair to the finished product to make them more attractive to their clients.
Clients always welcome 2D and 3D visualisations, and graphic designers ensure this by adding digital effects, backgrounds and even animations to designs. In other cases, graphic designers also use CAD tools to create commercial products such as logos or marketing materials.
The engineering industry is a sector that significantly benefits from CAD technology.
Engineers use the software throughout their entire design and engineering process. From the earliest drafts to the final product design, engineers constantly analyse manufacturing methods for the engineering components and tweak designs to complete their work at the highest level.
Engineers use CAD software to run simulations, figure out the tolerances of their designs and create different iterations of the product design before developing a real-life prototype.
Although CAD can seem intimidating at first glance, basic CAD is not hard to learn for beginners who wish to kick-start their CAD journey.
Anyone can create simple 3D models in most CAD software within a few days of proper training. However, basic engineering knowledge is required to understand how to optimise your designs, for product detailing, and analysis/simulation.
It also depends on which CAD software you use. There are multiple software options available on the market, and SOLIDWORKS is a popular option used by many around the globe. It's known for being easy to learn and use and has a long-standing reputation for its years of experience in the industry.
