Hello,

I tried to road a IGES model in my application, but have encountered faces with coinciding surfaces around the shared edge. My algorithm breaks because there is no angle at the edge.
Is there a way to merge the two into one face?

Hello Albert

Yes adjacent faces can be either coplanar or have identical surface. It would be the case if you, say, have divided a face.

We do not have built in functionality for that. I am not completely sure it is worth it. You can try merging wires for the two faces by removing the shared edge with IBRepWire_DG >(query) IBRepShape_DG.RemoveSubShape(), adding edges of the second wire with IBRepWire_DG.AddEdge()
and removing the second face with IBRepShape_DG.RemoveSubShape().

Regards
