~~vtn~~ 2012-06-18 21:51 developer ~0020722	Dear Vladislav, Please see if the problem is reproduced on current master.

vro 2012-06-20 08:36 developer ~0020739	The algorithm BRepOffset_MakeOffset has a restriction for this particular case. In other words, the operation can't be performed. A neighbour face of the "stop" face (they are in green in the pic 2_D1offset-2.png) represents a cylinder. Being offseted and enlarged the cylinder doesn't intersect the enlarged (but not offseted) planar "stop" face. So, a closed shell can't be constructed, the result is not reachable.

vro 2012-06-20 08:37 developer ~0020740	Dear Julia, what is your opinion on this bug (restriction of the algorithm)?

vro 2012-06-20 08:52 developer ~0020741	In addition, I put into CR22927 a small check operation to avoid a crash in case of no intersections between offset and enlarged faces.

~~jgv~~ 2012-11-02 16:16 developer ~0022085	Dear Mikhail, The bug is not reproduced (no crash). Please check it again on last version and modify the test script to make it OK.

apn 2012-11-08 13:58 administrator ~0022146	Dear BugMaster, Branch CR22927 (and products from GIT master) was compiled on Linux and Windows platforms and tested. Regression: Not detected Improvements: Not detected Testing case: offset compshape A4 - BAD (known problem) Test case was modified (necessary TODO was added) and new bug 23524 was created.
