| Summary | 0031437: Modeling Data - Offset surface throws exception when trying to evaluate at singularity point | ||||
| Description | The offset surface comes from Parasolid. The underlying surface is a B-Spline (apparently from surface of revolution) and has a singularity. Geom_OffsetSurface cannot be evaluated at the singularity point as the normal to the base surface cannot be evaluated. In fact, the normal can be evaluated - just need a more adapted algorithm to compute at singularity. | ||||
| Steps To Reproduce | In DRAW: restore bs offset os bs -2.5 or restore os An exception was caught 0000000003C12620 : Geom_UndefinedValue: GeomEvaluator_OffsetSurface::CalculateD0(): Unable to calculate normal ** Exception ** 0000000003C12620 : Geom_UndefinedValue: GeomEvaluator_OffsetSurface::CalculateD0(): Unable to calculate normal | ||||
