you may already know this, but if not:

I’m working on a huge laser cut wall screen for a client- it involves using curve boolean to combine thousands of curves into suitable cutter paths. I was getting failures from the cutter due to self intersecting curves, and viola! Rhino has a solution-

after you run your Booleans, before you export, select all curves and run _testcrvselfintersection

this will place a point on each self intersection allowing you to identify and fix them!

Better yet, also send in a bug report since CurveBoolean shouldn’t produce self-intersections.

will do chuck-
I can’t repeat it consistently - which is why I haven’t filed one yet-
