Description

Hello!
I trying to split the shape using a plane gp_Pln. When the plane passes through the edge of the shape, i'm catch an exception "NotDone" in BRepAlgoAPI_Section. I'm attached code and model, wich causes an exception.
Help me solve this problem.
Thank!

Steps to reproduce

Build a small example from archive Attachment 2 (ZIP).
Run this example with modelForExample.stp in command line parameter.

A Standard_Failure with the text "NotDone" can be handled. Unless there any sign of data corruption, an exception (thrown purposely) does not justify the severity "crash"

after importing your step file. model003 fails the bopcheck "SelfIntersection"
If i understand your step handling correctly, at the end of the for loop
TopoDS_Shape "shape" is set to the last shape of the file ("model003").

Thank you for your answer, Commenter 1. Exception may be was thrown because .step file incorrect. I wrote another example where BRepAlgoAPI_Section working correctly (without exceptions) but when i try split shape with BRepFeat_SplitShape i get an unexpected result. I attached this example: Attachment 1 (ZIP) (cmake project). There a cutting plane gp_Pln passes via Vertex. If i move the cutting plane the above or below this Vertex then i get the correct result. Can you comment on this behaviour a split-mechanism?

I'm sorry I haven't used BRepFeat_SplitShape, yet.
