Summary | 0022905: OFF 001 A6: 2d offset is not created due to invalid bisecting loci. | ||||
Description | This bug is detected in frames of the process of porting OCCT to Mandriva 2010. On this OS the case OFF 001 A6 is failed. However on Mandriva 2008 (reference OS) this case succeeded. 2d offset computation algorithm consists of two steps: 1. Bisecting loci computation 2. Intersection of offsetted edges with these loci and result computation. Deep analysis shows that the result of the first step is invalid on the both of OS: Mandriva 2008 and 2010 (see the attached figure). And the result of the second step basing on invalid input (the first step result) is unpredictable. It can give a good result (Mandriva 2008) or it can fail (Mandriva 2010). | ||||
Steps To Reproduce | To reproduce it in DRAW environment. load the wire from the case OFF 001 A6. mkplane f <wire> topoload f drawcont mat result v2d2 2dfit | ||||
