what are the steps for doing a closed volume in generative shape design of a panel

1. How to fill material at the places where cusp is happening and how many surface should be there for completing closed volume (A,B.C...).
2. Should i take offset of fillet areas too
3. why do we do draft analysis

Making a Closed Volume is one of the most difficult things to do. It requires that the object be totally defined with surfaces/faces, as well as all the edges must be totally defined with no edge-on-edge conditions. It is much easier and preferred to model with solids using the tools in the Part Design Workbench.
