Summary0003676: Pocket operations in Spiral pattern sometimes leave island on face
DescriptionUnder some conditions, pocket operations leave islands in the middle of the face (see attached screenshots). Using the zig-zag pattern instead of spiral works around the problem.
This has been reported on the forums here: https://forum.freecadweb.org/viewtopic.php?f=15&t=23763
This is 100% reproducible on a freshly installed and updated Ubuntu 18.04.1 and FreeCad daily from the PPA repository.
Steps To Reproduce- Open the attached Latch.fcstd file
- In Fab / UpperBodyJob / Operations001, switch between Spiral and Zig-zag patterns.
- Observe that with Spiral pattern, there is a rather large island in the middle of the face, while with Zig-zag pattern the face is milled completely.
