Full Version: A possible script for finding "holes" of a planar closed curve

Hi Michael.

Thanks a lot for the prompt reply!

Well...I too have considered a solution like the one you told me but for what I've simulated manually it seem not to work and also
maybe it's a little bit more complex than the solution I have though.

For example, using my example scene if I select all curves and apply a single PlananrSfr I get no useful resulting surfaces.
I mean that I can't get the main surface with the holes inside, but only many separated surfaces from each input curve.

Please check this brief video if you can : http://take.ms/QtaWo

Here you can get the example scene file : http://take.ms/uO3Eu




Thanks for your support :)

Hi Marco, yeah you're right, it turns out for a case with some of the curves intersecting each other like you've got there it won't make nested holes. So for that method to work you'd need to detect curves that intersect with your outer boundary and remove those from what you give to PlanarSrf. With the intersected curves removed you could probably use PlanarSrf to detect whether a curve is either inside or outside the outline though, if your other method doesn't work out.

Hi Michael.

Thanks a lot for your suggestion.

All in all is almost like the method I thought :)

Ok. I'm going to code a bunch of JS code for a first rough version of the script.

I think that it could be very useful for many use cases.

We'll catch up.

Ciao!
