I have two faces (see attached png) which lie on the same cylindrical surface and which share two edges. I need to merge them into one single face.
I tried to use BRepAlgoAPI_Fuser as well as the older version BRepAlgo_Fuser. Both failed. That is, both returned a shape concisting of the two original faces.
I also tried BRepAlgoAPI_Sewer which gave the same result.
Another idea was to build the face from scratch, using the edges of the original faces. I deleted all twin edges (one sibiling) and added all remaining edges to the BRepBuilderAPI_MakeWire. The wire construction seemed ok. I ran ShapeFix_Shape on the wire and tried to build a new face by using BRepBuilderAPI_MakeFace(gp_Cylinder, TopoDS_Wire), which failed.
How can I turn these faces into one?
Any hint/suggestion is welcome.
