Like Fredrik said, you should use the origin as the rotation point for parts and
other subfiles. Most parts have been written with the idea that the part would
be rotated around the origin.
Also, rotating subfiles on the origin allows advanced modelers to cleanly
control the functioning of their advanced models. When a section of the model
needs to rotate on a hinge or axle, they can put the rotating section in a
subfile, making sure the section is positioned with the rotation-point at the
origin.
One thing MLCad could do is to base the snap-to movements on the local
dimensions of the part being moved. So if I rotate a 2x4 brick 90 degrees
around X (so it's sideways), then move it downward, Y should change by +5, not
the normal +4.
This won't help with parts that are rotated at odd angles, but it will help in
many cases.

| Hi to all, since I played arround with MLCad the last couple of days to test it, I realy learned there is a mess with the rotations. MLCad currently try to rotate the part by its absolute center which sometimes works and sometimes not. So I feel I (...) (25 years ago, 23-Apr-00, to lugnet.cad.dev)
