How can I split a part by multiple surfaces?
I would like to split a single part into two parts by more than one surface. The reason is that while two small cuts would separate the part fairly easily, however creating a single surface to split the part would be complex to the point I don't even know how to approach it in general. So I want a way to take a body and some surfaces and cut the body using all the surfaces at once in useTrimmed mode so that I don't cut off random other parts of the shape. opSplitPart only taking a single tool is the main limitation I'm trying to work around.
Here is a manual example of the situation I am trying to handle: https://cad.onshape.com/documents/dac69982a60f83e429567279/w/a21ff6bef62be4030dfe93a9/e/ee7ce2784d7b50842f798214 (the cutting planes are highlighted)
Clearly, I could construct this so that the cuts are not needed, but my goal is to provide custom features that enable cutting and unfolding a solid shape similar to what is supported by the sheet metal tool. And doing so requires cutting up an existing and arbitrary body in a very controlled way. The first step of cutting up a part that has loops in it is the main issue that requires multiple cuts at the same time.
My current prototype is here if you want to look at it: https://cad.onshape.com/documents/b25934ce231bc7cc54b5f71b/w/22d6559f521f6dd2f91c3c2c/e/8e145788671a67d49b5b2a02 The problem with it is that it is insanely slow, due to my silly use of evCollisions. There is a more involved example at: https://cad.onshape.com/documents/146fd7ba5fc8678a0760f717/w/f9737f85504f7bdd029475c7/e/a5b719e8c9ae48517efc2320 It works sort of. But it's extremely slow (regen takes 5s for simple operations) and hard to control since the splitting techniques I'm using is very messy.
