Rhino 8 bug. The section tool ( _section) is not working correctly when sectioning a mesh. It pumps out multiple garbage lines that are not true sections of the mesh. Sometimes the lines will randomly follow the border of a polygon.
This is observed on a clean closed shrink wrap mesh.
I’ve also noticed the usual command line option of outputting closed lines is not present.

hi Robert, can you send that file? and the result of _Systeminfo?
I cannot repeat that behavior you are seeing here.
Sure, here you go.
Google drive linking the file as I have a string of tests in here showing the bug progress as the poly count goes up, so file is big. The poly count of the extracted sphere is for the original whole sphere of course.
Also the command line option to group or not is affecting the output, which is not normal behavior either.
As mentioned earlier please bring back the ‘joincurves by section plane’ option for _section.
side note, _project is not broken so that will be my workaround for now.

thanks for the sample, I can repeat that here.
RH-78758 Section is not working as expected
As for the missing option:
RH-78757 Section: missing JoinCurves option
thank you!
(damn why my NVDIA driver so old? fixing that now…)
