Archived issue #0025568

SIGSEGV in thrusections with edge without 3D curve

CommunityOCCT:Modeling Algorithmsclosed6 public notes

Description

The shape Loft-01-section is valid. The shape Loft-00-section is invalid (BRepCheck_No3DCurve). Creating a loft between those two causes a SIGSEGV.

versions tested:
6.7.0
6.8.1.dev-c0bd0de (master of 2014-12-05)

Steps to reproduce

pload MODELING
restore Attachment 1 (BREP) Loft-00-section
restore Attachment 2 (BREP) Loft-01-section
thrusections Loft 0 0 Loft-00-section Loft-01-section
donly Loft

The test case is bugs modalg_5 bug25568.

    0025568: SIGSEGV in thrusections with edge without 3D curve

    -Set algorithm flag NotDone if there is a non-degenerated edge with absent 3D curve.
    -Check IsDone flag in thrusection command.
    -Add test case bugs/modalg_5/bug25568.
