Hello all,
I want to use BRepBuilderAPI_Sewing class to sew two TopoDS_Face.
However the result is TopoDS_Shape still contains two TopoDS_Face.
I need it to be only one TopoDS_Face and only one Boundary rather than two.
Could anybody give me some advices to solve this problem.
Thank you in advance!

Sewing dont do what you want. You can use BRepAlgoAPI_Fuse.

Hi Oscar,
BRepBuilderAPI_Sewing:
------------ ------------
| 1 || 2 | Result | 1 | 2 |
| || | | | |
------------ ------------
You have 2 overlaping edges of 2 faces. Sewing check if one edge can belong to 2 faces. Bevor you have 8 edges, after sewing you have 8-1 = 7 edges. So one edge is shared to 2 faces, but there remain two faces.
BRepAlgoAPI_Fuse:
------------ ------------
| 1 || 2 | Result | 1 |
| || | | |
------------ ------------
You fuse 2 faces to one whole face.
Please correct me if I am wrong.
Regards,
Alex
