What is CAD?

CAD, or Computer-Aided Design, refers to the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.

Types of CAD software

1. 2D CAD: Used for creating flat drawings, such as floor plans and electrical diagrams.
2. 3D CAD: Used for creating three-dimensional models of physical objects, such as mechanical parts and architectural designs.
3. Parametric CAD: Allows designers to create models using parameters, which can be easily modified to generate variations of the design.
4. Direct CAD: Provides a more intuitive and flexible approach to 3D modeling, allowing designers to directly manipulate the geometry of the model.

Comparing Altium with traditional CAD software

While Altium Designer shares some similarities with traditional CAD software, there are also significant differences that set it apart. Here’s a comparison of Altium Designer with traditional CAD software:
