[LDCad] Idea for an LDCad script

[N. W. Perry]

Main question is this something that would be usable (seeing you''re the main end user at the moment )

For myself, I'm not as interested in detecting unintended collisions as in detecting intended ones. Basically as another form of snapping, so that you can move or rotate one part towards another, and it will stop exactly where the two parts touch. This is why I thought of it like an extension of the "put on ground" shortcut, because that's essentially moving a part (or model) downwards until it "collides" with the y=0 plane.

So for this idea of "collision snapping", or maybe better called "proximity snapping", you'd basically find the colliding surface of a nearby part and calculate from that a new "ground" plane. Then it would be the same mathematically as putting something on the ground—except that you might be moving the object on global axes while looking for the collision point on some non-normal plane.

At least, I think it would.
