Ha, sorry for that, but you know what MLCad did first?
It was rotating the part arround it's origin. But what happened?
Example: (the star is the origin)
+--+

*--+
now rotated ...
*-+
| |
| |
+-+
... and people (not all) complained: The view is so small and I can't see the
part anymore after rotating it ...
So I started to rotate the part over it center so that the center of the part
is on the same place after the rotation ... and this is where all the problems
started.
And now I revert back, it's better the part goes out of view, as if it is
miss-placed ... and Chuck wrote another article later than you wrote it, and
had I think a very good idea, I'll give it a try!
But thank you Steve ... at least your words prove the I have to go back to the
original rotation method.
