You will notice that CATIA provides three planes to let you
start your design. Actually, designing a part from scratch will first require designing a
sketch. Sketching profiles is performed in the Sketcher workbench which is fully
integrated into Part Design. To open it, just click the Sketcher icon and select the work plane of your choice.
The
Sketcher workbench then provides a large number of tools allowing you to sketch the
profiles you need. For more information, refer to CATIA-Dynamic
Sketcher User's Guide Version 5.
