Hello guys!
I want to build a surface through a couple of guide curves (green ones in picture) and section curves (red ones in picture). For those who are fimiliar with CATIA, there it is called Multi-sections surface. I looked through the BRepOffsetAPI package, but didn't find a class which satisfies my needs. For example BRepOffsetAPI_ThruSections takes a couple of sections, but no guide curves. BRepOffsetAPI_MakePipeShell takes a couple of profile curves, but only ONE spine.
Is there a way to do that in OCC? Thanks in advance!
Regards,
Alex

Hello Sharjith,
thank you for your response. Actually I need two sections and TWO guide curves (spines) between these sections. BRepOffsetAPI_MakePipeShell supports multiple sections but only one spine.

From the documentation, I guess you could set a second spine as an auxiliary spine...
void BRepOffsetAPI_MakePipeShell::SetMode(sonst TopoDS_Wire& AuxiliarySpine,
const Standard_Boolean CurvilinearEquivalence,
const BRepFill_TypeOfContact KeepContact = BRepFill_NoContact)
I haven't tried it though.

Hello PG!
Actually it worked! I was able to build the surface from my attached image with BRepOffsetAPI_MakePipeShell. By using the SetMode function you can add a second spine as Sharjith pointed out.

Hello Alexander,
I have a similar problem about multi section surfaces,my sections are more than two and there are three spines, is there a good function to generate a surface?
