If you are involved in any industry that requires design or engineering, you have likely heard of Computer-Aided Design (CAD) software. It is a type of software that provides designers and engineers with the tools to create detailed 2D and 3D models of their designs. With it, you can create precise and accurate models and easily modify, edit, and share with others.

CAD software has a rich history, dating back to the 1960s when computer-aided design tools were developed. Since then, it has evolved significantly by adding new features and capabilities regularly. Today, there are many different types of CAD software available in the market. Whether you are an architect, engineer, or designer, a CAD software package can meet your needs with its unique features and benefits. 

History of CAD Software

CAD has come a long way since its inception in 1957. At that time, artists and designers preferred the conventional ways of drafting by using pen and paper.

The first computer-aided design software was developed in the 1960s. It was used primarily for aerospace and automotive design. However, it was not until the 1970s that CAD software became commercially available. Initially, with 3D, the software was used only to produce drawings similar to hand-drafted drawings.

Due to the advances in programming and computer hardware in the 1980s, more applications of computers were used in design activities, most notably solid modelling. By 1994, over one million units of AutoCAD had been sold, with 350,000 users of CAD/CAM reported worldwide.

CAD Software

Today, the CAD market faces the emergence of free and open-source CAD software, including LibreCAD and FreeCAD. The commercialisation of CAD software and the decline in proprietary software led to difficulty amongst CAD developers in differentiating their software from each other. It will be interesting to see how CAD software evolves in the future as technology advances.

Types of CAD Software

When it comes to CAD, there are several types available to serve diverse design needs. Here are some of the most common types of CAD software:


2D CAD is used to create technical drawings in two dimensions. With it, you can create accurate and precise drawings that can be easily modified and updated. This type of software is commonly used in architecture, engineering, and construction.


3D CAD, on the other hand, is used to create three-dimensional designs for product design and architecture. With this software, you can create realistic and detailed models that can be viewed from any angle. It is commonly used in automotive, aerospace, and industrial design.

2.5D CAD

2.5D CAD is a combination of 2D and 3D CAD software which enables you to create designs that have depth and dimension but are not fully three-dimensional. It is commonly used in fields such as woodworking, metalworking, and jewellery design.

3D Wireframe

3D wireframe software is used to create wireframe models of three-dimensional objects. With 3D wireframe software, you can create basic models that can be easily modified. This type of software is commonly used in animation, gaming, and virtual reality.

Overall, the type of software you choose will depend on your specific design needs and your industry. Whether you need to create technical drawings, 3D models, or wireframe designs, one of the CAD software types is available to help you bring your ideas to life.

Key Features of CAD Software

CAD software has become essential for designers, architects, and engineers. With its advanced features, it has revolutionised the way we design and create technical drawings. This section will discuss some of the main features of CAD software that make it so valuable.

Design Tools

One of the most significant advantages of CAD is its design tools. These tools allow you to create complex designs, saving you time and effort. Its most common design tools include:

  • Innovative Tools: These tools automate the design process, making it faster and more efficient. They help you create accurate designs and reduce the risk of errors.
  • Parametric Modelling: This feature allows you to create a model that can be easily modified by changing its parameters. It is an excellent tool for creating complex designs that require frequent modifications.
  • Assembly Modelling: This feature allows you to create complex assemblies by combining multiple parts into a single design. It is an excellent tool for creating mechanical designs.

Visualisation and Rendering Tools

CAD software also offers powerful visualisation and rendering tools that help you create realistic 3D models of your designs. These tools help you:

  • Visualise your designs in 3D: This feature allows you to view your designs from different angles, making it easier to identify potential issues and make improvements.
  • Render your designs: This feature allows you to create realistic images and animations of your designs. It is an excellent tool for presentations and marketing materials.

Collaboration Tools

Collaboration is a crucial aspect of the design process. That’s why CAD software offers several tools that make it easier for you to work with others. Some of the most common collaboration tools include:

  • File Sharing: This feature is where you can share your designs with others. It makes it easier to collaborate on projects.
  • Markup Tools: These tools allow you to add notes and comments to your designs, making it easier to communicate with others.
  • Version Control: This feature lets you keep track of design changes and revert to previous versions if necessary. It is an excellent tool for managing complex projects.

Applications of CAD

CAD Software

Now, let’s move to the applications of CAD. CAD software is used in various types of industries and fields. Here are some of the most common applications of CAD software:


CAD software is widely used in engineering to design and develop products and systems. It provides engineers with the necessary tools to create, test, analyse, and modify 3D models of their designs as needed. It is used in various engineering fields, including mechanical, electrical, and civil engineering.


CAD software is also used by many architects since it makes their job easier. It creates detailed 3D models of buildings and structures, visualises designs, and makes modifications. This software also helps architects create accurate blueprints and schematics, which are essential for construction.

Fashion Design

On top of that, this software is being increasingly used in the fashion industry to create and design clothing and accessories. It allows designers to create 3D models of their designs, test and analyse them, and modify them as needed. It also helps designers create accurate patterns and measurements, which are essential for manufacturing.
