The LDRAW "group" (if you will) has created a color standard in ldconfig.ldr, a
text file describing common settings to be used by LDRAW utilities (the color
table, at this point). So far, few programs have supported it, with L3P and
LDView being notable exceptions.
MLCAD and LeoCAD being too applications that (IMHO) sorely need support.
I was getting ready to add support for it to ldglite* when I found LDView, and
haven't looked back. I would have recommended LDView to you for your (separate)
instruction-step query, but LDView doesn't (yet) support STEPs in models, it's
an all or nothing viewer. Other than that, it's extremely full featured
(including possible overkill in some areas -- Stereo imagery, for instance
:wink:) It's replaced ldglite for me for all tasks.
Anyway, back to ldconfig.ldr...
A bit more info can be found here:
http://www.ldraw.org/modules.php?op=modload&name=News&file=article&sid=299
and here:
http://news.lugnet.com/cad/mlcad/?n=2162
But basically it's an external way to define how colors are named and used.
I am currently working on a version of ldconfig.ldr that has the official
numbers (where they don't conflict with existing numbers), names, and RGB
values. I should be done in the next week or so, and I'll see about convincing
the ldraw.org folks to host it as an "alternative" ldconfig.ldr file. (Either
way, I'll be hosted it next to my color chart doc at
http://alumni.cse.ucsc.edu/~dulcaoin/LEGO/LEGO-Color-Chart.pdf)
I really wish a comment indicator such as // had been added to the format, but I
haven't seen one; that would have allowed some nice commentary when I changed
names to match LDRAW usage, but I haven't such a syntax presented.
Hopefully, this will address some of your issues? The next steps would be
getting ldconfig.ldr support into MLCAD and LeoCAD.
