Summary0023149: GeomAPI_IntCS bug?
DescriptionI've used GeomAPI_IntCS to find intersections between a surface and a line, and I obtain intersection points out of the surface.
Steps To Reproduce-Load the iges file attached.
-Apply the funcion with the parameters showing in the dialog.
-Test that the intersection point found is in the air.
TagsNo tags attached.

Ana, you have not attached the IGES file, so the issue could not be checked / reproduced.

However, from your code it seems you are doing wrong thing: you intersect the line with a surface, while obviously you want to intersect it with a face (which is part of the surface restricted by edges). It is very likely that the surface on which your face is based extends outside of the face as you see it, and intersection is found correctly.

Please try using class IntCurvesFace_Intersector instead of GeomAPI_IntCS.

That's right. The face is based in a more extended surface.
I tried to simplify the example, so I erased one face.
Anyway, I found anothers extrange behaviors in the complete surface.
I've attached in the "CompleteSrf.rar" file.

I'll try IntCurveFace_Intersector anyway. Thank you very much.

It's not a bug, but a bad use of the function.
