Hi Burr, does it generate the missing ones if you turn off the "Trim" checkbox?



It looks like offset is having difficulty detecting the self-intersecting spot on this particular shape. If this happens you can turn off Trim and then get some pieces to work with.

That was it! And I didn't manage to use my dedouchary skills to equate the "trim" to getting the "compute anyway" result...

Just what I needed. Thanks for the help. Sorry to bother....
