Whenever you come across CAD software, they run differently depending on the geometry. Every program has horizontal, vertical, and depth coordinates. These appear along the X, Y, and Z axes, respectively. Once designers start using the software, they can create 2D or 3D models through raster or vector-based graphics.  

Now, regardless of whether you’re a student or an amateur, you can always download and install free programs that can assist you with designs. For instance, you can certainly use Blender which is capable of creating high-quality designs just like AutoCAD. 


CAD History

The birth of CAD can be traced way back to the period between the 1940s and the 1950s. It was during those years, several developments led to design-related capabilities. However, the approach was named in 1959 by an MIT researcher, Douglas T. Ross. But the realm of design seemed to transform in 1963. 

When a computer scientist, Ivan Sutherland, developed SKETCHPAD, individuals were able to interact with the computer through the first graphics program. Once they started using the light pen, the drawing used to appear on the CRT monitor. Here’s when people became aware of what CAD software can do. Subsequently, things started to change with every passing year.  

In the 1970s, people started using CAD more than just for research purposes. Aerospace and automotive organizations also started developing their own software. While CATIA was developed in 1977, Autodesk was created by John Walker in 1982. However, the evolution of CAD software didn’t end in the 1980s.  

As CAD software continued to evolve throughout the 1990s, it was accessible to many large-scale companies. The popularity also grew in the late 1990s and 2000s. Eventually, companies developed open-source CAD programs for everyone across the globe. 


2D & 3D CAD

2D & 3D CAD

Most of the time, designers embrace CAD only when they have to create 2D drawings and 3D models. Now, let’s go through what we mean by ‘2D’ and ‘3D’. 

While you’re observing 2D CAD models, these are drawings with two dimensions. They give a clear representation of the layouts that have to be reproduced during the building phase. You will notice these models in industries like civil engineering, interior design, fashion, and landscaping. For instance, if architects have to create floor plans for residences and buildings, then they will spend time creating 2D blueprints, HVAC diagrams, and wiring diagrams. Now, let’s proceed with the application of 3D models. 

As you come across 3D CAD models, these present details regarding assemblies and components of different objects. The visual representation will also help to know how the object operates. Hence, teams think of developing 3D models in domains like manufacturing and automotive models. 


Advantages of CAD

There are several benefits that CAD offers for designers working in various industries. Let’s take a quick look at every benefit, one after the other. 

Enhanced Design Accuracy and Quality

When you use CAD software, it enables you to visualize designs through the presentation of 2D and 3D models. In comparison to actual drawings on paper, these models are accurately presented on the computer screen. By using a vast range of tools and functionalities, designers can also create complex shapes and surfaces. This is valuable to designers when they have to completely test and make modifications to models before bringing the digital design to life in real-time. 


Streamlined Revisions

Streamlined Revisions 

Imagine how time-consuming it might be when you wish to incorporate changes in a drawing on paper. But, through CAD, changes in drawings can be made with ease and in less time. While designers use CAD to identify errors, they can rectify them before prototypes are designed. Experienced designers can also run simulations using the CAD software to test if there are any problems.

Boosting Productivity in Engineering

As compared to the traditional approach of designing anything, computer aided engineering enables designers to work at a faster pace and in a smarter way. They no longer have to draw the design manually, which could otherwise take up a lot of time. Apart from editing, designers can test the design accurately before proceeding with development. This serves to be beneficial to companies, which can think about recruiting less designers when the affordable designing process can be led by the software. 

Improved Collaboration and Communication

Soon after the designer completes the CAD drawing, the software facilitates instant sharing with other team members. The drawing can also be shared with those who are working from remote locations. With the design history in place, team members can incorporate perceptions at every stage of the process. But, with time, organizations are now using cloud technology to make design accessible at any instance. Professionals don’t have to ever think about sharing the designs all by themselves. 

Effortless Design Documentation

While using the CAD software, professionals can document every minute detail of the design. These details can include angles, dimensions, and measurements. Professionals can later refer to the details and reuse them in future projects. The software further allows for the saving of subassemblies, along with components, for future reference. 

Enhanced Design Understanding

In comparison to sketches on paper, 3D models, designed through CAD, are quite easier to understand. On the contrary, when designers have to present physical sketches completely, they have to be represented in different ways. Beyond this, CAD software can enable professionals to understand the 3D model even when they don’t know anything about designing. This also means that marketing professionals can present the models to prospective clients when they are pitching a particular product. 

Accelerate Manufacturing Process

Besides improving the design process, industrial CAD can help expedite the manufacturing process. With the help of compatible computer-aided manufacturing (CAM) software, the worker can check the tools and fixtures designs path for CNC machining and input relevant files. A bit later, CAM software can create the machine code for production, thereby offering a more efficient method compared to conventional manufacturing processes. 

Specialization in Design Expertise

While many companies across industries use CAD, there are many specialized programs to do an outstanding job of designing. For instance, civil engineers can use AutoCAD Civil 3D for tasks like land development, road designs, and infrastructure projects. In addition to features like creating and analyzing surfaces, AutoCAD Civil 3D can help with data management for different projects. 


What is CAD Used For?

In the present era, industrial CAD is used in many domains due to its various capabilities. Now, let’s check out the common uses in different sectors.  

Building Information Modeling (BIM) with CAD in Architecture

When architects need to rely on complex and accurately prepared drawings, CAD can be a fundamental tool. Some tools, like ArchiCAD and Revit, are useful because BIM (Building Information Modeling) workflows help to improve productivity. BIM is nothing but an approach through which architects can integrate geometric and non-geometric information about a project. Once a digital model is created through BIM, it can be shared with business leaders for a closer look.

From Concept to Creation in Product Design

Among the suite of CAD software, Fusion 360 and Inventor can help designers visualize industrial products from all angles and comprehend how they will actually work.
