Common CAD software used in automobile design includes CATIA, SolidWorks, and AutoCAD.
These tools help engineers create precise 2D and 3D models of vehicle parts and assemblies.
They are widely used for designing, testing, and improving automotive components efficiently.
In this article:
Automobile design relies heavily on CAD (Computer-Aided Design) software to create, simulate, and refine vehicles before physical production. Different tools are used depending on whether the focus is concept design, surface modeling, mechanical design, or simulation.
