Computer-Aided Design (CAD) software is a technology used by professionals in various fields such as architecture, engineering, and manufacturing. It helps create designs through an automated process instead of manual drafting. With CAD software, users can view their work in 2D or 3D models, providing a clearer understanding of the project.
Using this software saves time, reduces errors, and makes it easier to create complex designs. Additionally, it allows for quick modifications or revisions of designs.

What is CAD Software?
CAD, which in full means for Computer-Aided Design, is a computer program that helps in designing, developing, and manufacturing parts and equipment used in production. According to Autodesk, CAD is “a technology for design and technical documentation that replaces manual drafting with an automated process.”
The definitions above explain the role of CAD software, but they are just an introductory idea. CAD software not only replaces manual drawing (known as manual drafting) but also plays a crucial role in the entire production process.
With the help of CAD software, design engineers, architects, hobbyists, and even students can create designs easily. Computer technology simplifies the design process and facilitates faster and easier communication among all project members. In other words, it enables collaborative work, where everyone—from architects to engineers—can use the same platform.
This technology has impacted the design and manufacturing industry so significantly that it is used in many fields. CAD modeling tools are employed in aerospace, interior design, dentistry, automotive, architecture, and many other industries.
Next, we will learn about the types of CAD software and their areas of application.
Types of Top Computer-Aided Design (CAD) Software
Most CAD software is designed for specific functionalities. However, they can generally be classified based on dimensions (e.g., 2D and 3D design) and modeling techniques (e.g., 2D drafting & drawings versus 3D modeling).
2D CAD Software
When we referred to CAD as replacing hand-drawing, we were mainly talking about 2D CAD software. Like hand-drawing, objects created using this type of CAD are produced according to technical drawing rules. The difference is that one process is manual, and the other is automated. 2D CAD software comes with a library of geometric shapes, making it easier to design complex objects.
Although 2D CAD still has some applications in traditional industries (such as mechanical, electrical, and aerospace engineering), its primary focus is on architecture and civil engineering. Examples include floor plans, building permits, etc. Some free 2D CAD software includes QCAD and LibreCAD. Other popular software includes AutoCAD and Bentley Systems’ MicroStation.
3D CAD Software
3D modeling software comes in various types depending on specific functions and levels of detail. Generally, 3D CAD programs create a graphical projection of an object. These realistic models help understand design problems and allow virtual solutions. Due to its level of detail, 3D CAD is most suitable for representing complex mechanical parts and assemblies. Popular 3D CAD software includes Autodesk Inventor and Bricsys.
Types of Modeling
Based on modeling techniques, there are mainly three types:
Wireframe Modeling
This type of CAD software uses lines and curves to create a skeletal internal structure of an object. While it is a quick way to represent a point, creating a fully detailed model is difficult. Therefore, it is less commonly used.
Solid Modeling
This is the most widely used in mechanical and 3D printing industries. It allows the creation of fully detailed models and calculates the object’s dimensions.
Some subtypes of solid modeling include:
Constructive Solid Geometry (CSG)
Boundary Representation (Brep)
Surface Modeling
This is a complex modeling method, popular for architectural design and rendering. Some applications include custom products, ships, automobile body parts, etc.
Key Features of CAD Software
2D Drafting & Drawing: Users can create precise flat drawings, such as floor plans and circuit diagrams. Essential for architectural and electrical engineering designs.
3D Modeling: Allows creation of three-dimensional objects in virtual space. Crucial for mechanical engineering, architecture, and animation.
Parametric Modeling: Users can define specific design parameters and constraints. When design variables change, the model updates automatically.
Surface Modeling: Focuses on the exterior surfaces of models. Suitable for automobile exteriors or complex designs.
Solid Modeling: Enables creation of solid components and assemblies. Essential for manufacturing and engineering.
Simulation & Analysis: Provides tools to simulate physical behaviors like stress, heat, and fluid dynamics.
Rendering: Converts 3D models into high-quality images or animations.
File Compatibility & Interoperability: Enables file exchange across different systems and applications.
Customization & Extensibility: Users can customize the interface and functionality.
Collaboration Tools: Multiple users can work together on the same project, often cloud-based.
Revision Control: Tracks design changes and allows reverting to previous versions if necessary.
Automated Documentation: Automatically generates technical drawings and documentation from 3D models.
BIM Compatibility: Essential for architectural CAD software to comply with BIM standards.
How to Choose the Best CAD Software
Feature Set That Meets Your Needs
A good starting point when looking for the best CAD software for your company is to define your needs. Although this may seem obvious, many CAD users do not take the time to evaluate which features they actually need from the software. According to a survey by engineering.com, having CAD software that meets your product development needs is essential.
List your requirements: which features must the toolset have? Do you need advanced features such as additive manufacturing or parametric modeling? Do you require compatibility with multiple operating systems like Linux and Windows, or extensive data management for numerous designs? And what about cost? Ask these questions to guide your research—what do you need, what do you want, and what is your budget?
Ownership and Maintenance Costs
Even if you can get software with all the features, it’s important to consider your budget. Generating profit is the primary goal of any business. You wouldn’t want your annual investment to exceed potential revenue. Check the ownership and maintenance costs of your options and ensure they align with your budget.
Interoperability With Other Solutions
Top product designers and companies strive to avoid problems by minimizing potential issues. A common challenge CAD users face is converting files from one system to another. Use CAD software that can easily import files from other systems so you can stay ahead over time.
Active Support and Community Resources
An often overlooked criterion for selecting the best CAD software is the availability of community resources and 24/7 real-time support. You don’t want to wait days after sending an email inquiry or struggle to find company-specific answers.
In addition to direct support, check what types of educational resources are provided. Do they offer tutorial modules with real-life examples? Do they show how to integrate and use different file formats and 3D printers? Verify their support and educational materials before making your decision to ensure your needs are met.
Conclusion
Ultimately, the decision is yours. Different organizations may prioritize different factors or criteria. Again, everything depends on understanding your needs well. Choosing the best CAD solution depends on how well you understand your company’s requirements. Don’t focus on limited criteria, and don’t make emotionally-driven decisions based on brand preference. Check everything necessary to fully empower you and your team.
Additionally, if you want to practice or improve your skills, there are many free CAD software options readily accessible.
