Yes. No. ;-)
There's still a problem with mirrored sub-assemblies.
Suppose you have an aeroplane, Plane.ldr:
1 2 0 0 0 0 0 1 0 1 0 -1 0 0 2445.DAT
1 16 0 -8 0 1 0 0 0 1 0 0 0 1 Wing.ldr
1 16 0 -8 0 -1 0 0 0 1 0 0 0 1 Wing.ldr
Wing.ldr:
1 4 -80 0 -20 0 0 1 0 1 0 -1 0 0 3933.DAT
1 14 -80 0 60 0 0 1 0 1 0 -1 0 0 3934.DAT
UnMirrorStuds generates Plane.ums:
1 2 0 0 0 0 0 1 0 1 0 -1 0 0 2445.DAT
1 16 0 -8 0 1 0 0 0 1 0 0 0 1 Wing.ums
1 16 0 -8 0 -1 0 0 0 1 0 0 0 1 Wing.um2
Wing.ums:
1 4 -80 0 -20 0 0 1 0 1 0 -1 0 0 3933.DAT
1 14 -80 0 60 0 0 1 0 1 0 -1 0 0 3934.ums
Wing.um2:
1 4 -80 0 -20 0 0 1 0 1 0 -1 0 0 3933.um2
1 14 -80 0 60 0 0 1 0 1 0 -1 0 0 3934.DAT
I can let L3P take 3934.ums as an alias for 3934.dat, so far so good.
For 3933.um2 I believe I can generate POV code to create a LGEO part
with mirrored studs by temporarily defining a mirrored lg_knob (the LGEO stud)
before sourcing the LGEO part.
But UnMirrorStuds is "too clever" and it detects the double mirroring
of 3934 and simply puts 3934.DAT in Wing.um2.
But here we need an LGEO part with mirrored studs - perhaps
UnMirrorStuds can put 3934.um2 in Wing2.um2 ?

| (...) Thanks for the info. After further consideration, I realized that there is one other thing that will prevent the -lgeo option from working properly, even for models that don't have mirrored sub-assemblies. Any parts in the part library that (...) (21 years ago, 11-Jul-03, to lugnet.cad.dev)
