Summary

0025426: GeomFill_Pipe produces artefacts

Description

Hello!

GeomFill_Pipe sometimes produces strange artefacts. I have observed, that the more complex the base curve gets (as the number of control points increase), the more often these artefacts appear. Please see my code snippet:

--------------------------------------------------------------
GeomFill_Pipe gfp(theCurve,5);
gfp.Perform(Precision::Confusion(),Standard_False,GeomAbs_C1,BSplCLib::MaxDegree(),1000);
--------------------------------------------------------------

I have added a picture of the artefacts and the .brep-File containing the base curve.

Regards
