What is a CAD software?
Computer-aided design (CAD) software is a computer tool that allows you to create, modify, analyze, and optimize designs.
They are used in many sectors: architecture, mechanical engineering, electronics or product design.
CAD software offers a digital platform where designers can create 2D and 3D models of their designs.
These models can be manipulated, tested, and refined interactively, allowing designers to experiment with different ideas and make changes quickly.
Among the main functionalities of CAD software, we find:
- 3D modeling : creating detailed three-dimensional representations of designs.
- Parametric modeling : definition of relationships and constraints between the various elements of a design.
- The assembly : combining multiple components to create a complete model.
- The simulation : virtual test of the behavior and performance of a design under real conditions.
- The generation of plans and technical documentation : automated creation of drawings and files required for manufacturing.
CAD software allows designers to work more efficiently, reducing errors and speeding up the development process.
They also facilitate collaboration between the different teams involved in a project, thanks to the sharing of digital files.
They are essential tools for design professionals, allowing them to bring ideas to life and create innovative products faster and more accurately than ever before.
