My problem with the studless subpart is that we'll set a precident that may
be deterimental.  What if we have 2 32x32 baseplates that are mirror
images?  would we have two files with 100+ stud that are exactly the same
with the exception of the part being mirrored?

  A fair point, but how often would that happen, realistically?  Enough to be a
problem?  Even if one or two parts eventually turn up like that, why would the
whole system have to be jettisoned for those few exceptions?

This will only serve to increase render time since we mow have to parse and
extra subfile.

  I'm not sure that this is a persuasive argument. Until not long ago I used a
super-sluggish Pentium 120 CPU, and I never had a discernable problem with
parsing delays of this sort.  Even the slowest CPUs on the market today are
much, much faster, so delays of a few nanoseconds don't give me much pause, so
to speak.

I definitely would not hold a part because the studs aren't all lined
up!

I agree that this is a pretty petty reason for a hold vote

  Absolutely agreed!
  Conversely, if a pair of mirrored parts were submitted as a subfile + two
distinct stud layouts, would the parts be accepted in that form?

If LDView can correct for this, any program can.  The extra work and subfile
clutter are just not worth it for a nice-to-have-but-not-required bonus feature.

  Well that's definitely true.  If a fix can be generated without radically
restructuring the way mirrored parts are created, then by all means that's the
way to go.
  By the way, why is subfile clutter a problem?  There are a zillion minifig
torsos that I never use, but I don't delete them because they don't cause me any
real trouble.  I almost never look in my s\ directory, so anything that goes on
in tehre is basically irrelevant to me.

(...) And mine as well. If LDView can correct for this then so can any other program. The stud logos are a bonus feature offered by many programs but are not officailly supported by the LDraw spec. (...) This further supports my position on this (...) (21 years ago, 2-Jul-03, to lugnet.cad.dev)
