Which software is better CATIA or solidworks?

CATIA is software suite for computer-aided design. It provides computer-aided manufacturing & engineering, 3D modelling, and PLM (product lifecycle management), etc. Whereas Creo is a computer-aided design application supporting. It consists of apps, which delivers a varied set of capabilities for a user role within product development.

Yes, CATIA does not require learning AutoCAD, it is a fully parametric software. But by practicing AutoCAD you can clear the concept of 2D drawing & Drafting.

Yes, CATIA Mechanical Designer is a suite that manages the overall mechanical design processes for product designers, mechanical designers, and engineers. It will part design, assembly creation, 3D mock-up review, mechanism motion, drawing generation, etc.

CATIA stands for Computer Aided Three-Dimensional Interactive Application. CATIA uses C++programming language.

CATIA is a computer-aided design (CAD) software that allows you to build structures and models of various objects. This software has tools for surfacing and 3d modelling, calculation of life cycle management, simulations of any product etc. Whereas AutoCAD is software that allows you to design and draft several computer applications. The software allows you to precisely design civil infrastructures, import files from other platforms, calculate area, Mass, Volume, etc.
