Summary | 0028687: Offset for open wire is built with incorrect direction | ||||||||||||
Description | If the source wire is oriented correctly then the offset direction must be on the left side from the wire direction if offset value is negative and on the right side in case of positive offset value. However, in some cases, this rule is not satisfied (see Steps To Reproduce). | ||||||||||||

Cases ## 1 and 2 are reproduced on the current MASTER. Fix for the issue 0028677 solves this problem particularly. However, CASE # 3 is failed even after 0028677 will be fixed. The possible reason is in hard code in KPartCircle(...) function (see src\BRepFill\BRepFill_OffsetWire.cxx). |
