LDCad META commands.

[Roland Melkert]

From the user point of view: that would be great, snapping in LDCad works. The only what we need to keep is a way to improve it in future - I always wonder when somebody wants to cut something in an official stone

It would help to get snap info from the get go during part modeling.

* rotation snapping (a part snaps while you rotate it - I described it in some older LDCad thread)
* multisnap - while moving a bigger submodel, it snaps so all bricks snap. Including the (slight) model rotation.

This is what i called "occupation exclusion" above, technically it doesn't need any extra information it could be done using the current information but it would be extremely cpu intensive. So I'm looking into extra info which could help it speed up ether at the part level or by some sort of caching in the model it self.
