[LDCad] Restricting parts to whole number x,y,z script

[Ironmatt]

This is due to the fact that Stud.io is not always using the LDraw file as model but a file from another source (LDD meshes, LEGO, ...) and these files may have a different origin.

That's good to know, but I wonder why. Pretty much all the parts in stud.io also have ldraw models, is it just that parts are already in the program, so they don't feel like updating them?
