Kunda1 2017-08-28 19:38 administrator ~0010032	@sliptonic please weigh in @marc thanks for the report. Please read https://freecadweb.org/wiki/Tracker to familiarize yourself with how to post bugs/features. Thanks

marc 2017-09-05 06:45 reporter ~0010068	Any update on this? It appears the algorithm doesn't play nice with little tools like my engraver.

Kunda1 2017-09-05 19:47 administrator ~0010069	@marc again please read tracker guidelines. You need to add your full FC info (Help > About FreeCAD > Copy to clipboard) also it is customary to let the devs know on the forum first. That's how you get more publicity about issues. CC @mlampert care to weigh in?

mlampert 2017-09-05 20:16 developer ~0010070	I'm afraid this is a known issue with no solution as of today (https://forum.freecadweb.org/viewtopic.php?f=15&t=23492). OCC just released a new version and we still have to see how it'll behave. In order to reproduce, can you attach your FC file please and your full version info (see Kunda1's comment above on how to get that)?

mlampert 2017-09-07 20:58 developer ~0010089	I've compiled FC with the latest version of OCC (7.2) and the issue seems to be resolved - however I cannot verify/test without having the actual file.

mlampert 2017-10-07 23:33 developer ~0010260	Fixed by new pocketing operation https://github.com/FreeCAD/FreeCAD/pull/1004
