Beginner-level CATIA V5 tutorial aimed at improving your 3D modelling skills to the next level. I tried to simplify the steps while making the workflow as efficient as possible. At the end of this tutorial, you would be able to:
1. Create Points
2. Create Splines
3. Create revolute surfaces
4. Create Projections curves along a direction and normal to surface
5. Create Multi-Sections Surfaces
6. Split a curve using point on curve
