Hi Dalton, I missed a small nuance in your code in my last two posts:
TopoDS_Face(... Should be TopoDS_face(... Note the lower-case "face". Can you try it and confirm you no longer get an error? I'd like to make sure there is no pythonOCC/OCC issue here. After analyzing the OCC documentation, BRepBuilderAPI_MakeFace returns a TopoDS_Face. Therefore, my original directions to convert with TopoDS_face before sending it to stepwriter were unnecessary. (I'm learning something here too.) So, I believe your latest/greatest code is fine, and there is no error in your surface. Could you still try TopoDS_face(..., though, to ice this off?
