@yorik do you mind checking this out?

Hm must be some safety check missing... I'll handle this!

FWIW it seems this shape is immune to a boolean operation also (the only message is "Boolean Operation Failed").

 I also get an error if I try to Draft Clone pear001.

Traceback (most recent call last):

I don't see the attached file anymore, it might be because of the tracker failure some weeks ago... could you reupload it?

Probably my error. Attaching now.

Oh I see, the problem is that the attachment is too large. It seems the tracker must reject it without an error.
I have posted it to the web here: http://vectro.org/3023.fcstd

Thx for the heads up about the tracker. We’re testing to see if we can reproduce the tracker behavior. Also, thx for the attachment.

Thanks for the file. I now added a couple of safeguards to help the user to select things correctly and avoid the error above. The cutplane operation now works on your shape.

Note that these shape files thatare generated from mesh objects will rarely give very good results with booleans, unless they are very carefully modelled. This one has a number of defects that won't produce a very good result..
