I noticed when looking at part 6002 posted at the tracker that one of the
studs is rotated 90 degrees when compared to the other three.  This is only
visible if you use a program that supports stud logos (such as my LDView
program).

Is this something that should be considered during part authoring?
Obviously it will only be visible in a few programs (LDView and high-quality
mode for L3P are the only two I am aware of, but there may be more).

BTW, L3P has a problem with mirrored parts:
Part 3935.DAT "0 Wing  4 x  4 Right" only has one line:
   1 16  0 0 0  -1 0 0  0 1 0  0 0 1  3936.dat
which is a mirror of the left wing.

If L3P were to render the stud logos correctly, it would have to inline
the part tree down to the studs.
But L3P doesn't walk the tree, POV does, and I haven't been able
to figure out how to test whether an actual instance of an object is mirrored or not.

LDView renders 3935 correctly.

(...) Hmm, isn't there any abs[-olute value] function that one could insert somewhere so that the x and z values for the studs are either both positive or both negative? /Tore (22 years ago, 19-Jun-02, to lugnet.cad.dat.parts)
