Hi and welcome to the course CATIA Part Design Workbench : deep learning from A to Z 

first of all ,CATIA® is the leading engineering and design software in the world for product 3D CAD design excellence.It is used to design, simulate, analyze, and manufacture products in a variety of industries including aerospace, automotive, consumer goods, and industrial machinery, just to name a few. It addresses all manufacturing organizations, from OEMs through their supply chains, to small independent producers.

secondly ,The Part Design Workbench of catia provides advanced tools for modeling complex solid parts and is based on a feature-editing methodology. It is mostly focused on, but not limited to, creating mechanical parts. It is intricately linked with the Sketcher Workbench.

finally , after taking this course you will be able to design 3d models using the most advanced features of catia v5 part design workbench like : dress up features , sketch based features , transformation features and other features.

kind regards.
