Help! Projection of face or shape on surface - Another problem?

Dear Stephane

Thank you for your help first.

After using HiddenLine algorithms, I got the projections of all edges including OutlineEdge. But I have another problem: I want to get the adumbration of it. When I fused the VCompound(visible sharp edges) and OutLineVCompound(visible outline edges) and other visible edges, I don't know how to get borderline of this fused shape(a compound of shapes). In fact, my objective is get the projection of a shape which should be, I think, a face, right?

Can you give me some directions? Thank you in advance.
