3D CAD Software

What is 3D CAD Software?

Three-dimensional computer-aided design, or 3D CAD, is a technology that automates the process of design and technical documentation, replacing manual drafting. This technology is widely used by professionals such as architects and engineers to create precise representations and visualizations of objects using a collection of points in three dimensions on the computer. 

Types of 3D CAD Software

There are various types of 3D CAD software available in the market today, each with its own unique features and applications. Here are some of the most common types of 3D CAD software and examples:

Parametric CAD

This type of 3D CAD software is based on parameters, which allows designers to make changes to a design and have the software automatically adjust all other elements affected by the change. Examples include: SolidWorks, Autodesk Inventor, CATIA, Onshape, FreeCAD and Tinkercad

Direct CAD

Unlike parametric CAD, direct CAD does not rely on parameters. Instead, designers can modify the design by directly manipulating its geometry, allowing for more flexibility and creativity.

Some examples of Direct CAD include SpaceClaim, PTC Creo and Onshape

Solid Modeling

This type of CAD software allows designers to create 3D models with solid geometry. Solid models are used to create physical prototypes and can be used for various manufacturing processes. Examples include CATIA and Rhino.

Surface Modeling

Surface modeling is used to create complex shapes and curves that are difficult to achieve with solid modeling. It is commonly used in the automotive and aerospace industries.

Examples include Ansys and SIMULIA.

Assembly Modeling

Assembly modeling allows designers to create assemblies of multiple parts and components, which can be used to test how they fit and work together. Examples include SolidWorks and Autodesk Inventor.


While 3D CAD software is used primarily for creating 3D models, 2D CAD software is used to create 2D drawings and blueprints. Examples of 2D CAD Software are BricsCAD, NanoCAD and QCAD.

Benefits of 3D CAD Software in Modern Manufacturing and Design

3D CAD software has several benefits on modern manufacturing and design, including:

Enhanced Design Capabilities

With 3D CAD software, designers can easily create complex and detailed designs, enabling greater innovation and creativity in product development. They can manipulate 3D models to explore and test design concepts quickly.

Increased Efficiency

3D CAD software has significantly increased the efficiency of the design process, saving both time and money for manufacturers. With this software, designers no longer have to rely on manual processes, such as drafting and physical prototyping, which can be time-consuming and expensive.

Improved Communication

Improved communication is another significant benefit of 3D CAD software. With this technology, designers, engineers, and manufacturers can easily collaborate and share designs with one another.

This eliminates the need for traditional design reviews, which can be time-consuming and prone to errors. Instead, stakeholders can view and analyze 3D models in real time, making it easier to identify potential issues and make necessary changes.

Better Visualization

3D CAD software provides designers with a more realistic and detailed view of their designs. With the ability to view a design in 3D, designers can identify potential issues that may not have been apparent with 2D drawings. This helps them make necessary modifications and adjustments before the product is manufactured, reducing the risk of errors and costly mistakes.
