Poly Intersect Cut

[komplex]

I want to write a script that will take 2 poly objects that are intersecting and perform a cut on the last selected object. If I was using 2 spheres it would be like making one live and drawing a circle on it then tracing the circle with the splitPolyTool.

I just need to know which functions I should be using to find the area that is intersecting.

wouldn't it be easier to duplicate both objects, do a boolean>difference on the first pair, a boolean>intersection on the second pair then polyMerge the two resulting objects together?

you'd have some new polygons on the "inside" but these would be easy to remove? (I think off the top of my head!)

I've just tried it and it works beautifully even with an "open" object.. it seemed to be exactly what you're trying to achieve..

Here you go, isn't this pretty much what you want?

Select TWO polygon mesh objects, the FIRST selected it the "cutter" and the SECOND selected object is the one to be "sliced".

One side effect is that both objects have their construction history deleted. other than that, there's next to no error checking, an odd warning at the end about multiple "-ch" flags and it's only been tested on Maya 3. sorry...

works a treat though as a quick test knock-up...
