Now then, some follow-up questions: 1) Is my subpart file name kosher? I much
prefer this to s/6898s00.dat. After looking I couldn’t find much of a clear
answer on whether there’s a standard for this beyond following the part
number with s. 2) How would one go about submitting a part with subparts to
the tracker? I didn’t submit 6251.dat myself, so the tracker submission
process is unknown to me. (For that matter, I have a minor update to 6251.dat
to share.)

Great work.
The subpart naming standard(s)n are documented at
http://www.ldraw.org/library/tracker/ref/numberfaq/
So, I’d rather your
subpart were named s6898s01.dat.
Submitting a new part to the Parts Tracker is easy. You need to register as an
LDraw.org user (at http://www.ldraw.org) and then request Steve Bliss or I
(via parts@ldraw.org) to set you up with Submitter rights.
On the Parts Tracker submission page there is a set of radio buttons for the
“Upload destination” - just select Parts\s for the subpart. It doesn’t matted
which order you submit; the tracker figures out the dependencies.
To submit an update to an existing official part (such as 6251), please send
this by email to parts@ldraw.org.

I’d like my next project to be x79.dat,
which raises some intriguing questions. This part has curves etched into the
sides to simulate bunched fabric. If I went ahead and modeled it without
looking into a better approach, I’d be overlooking a wonderful opportunity.
The problem of producing an etched curve on a surface is just another form of
the problem of producing raised lines on such a surface--the technique that
would be needed to produce hair pieces. Whoever comes up with a tool that can
gracefully produce a surface with etched/raised splines according to user
specifications will have opened the door for good part authors to “easily”
create textured minifig hair. The main questions to my mind are how best to
implement such a tool, and what information it would require to do a good
job. Clearly this will require a lot more thinking out loud.

You make some good points here - precisely those which have prevented many of
the hairpieces from being modelled. Even a tool that acceptedthe co-ordinates
for pair of splines and generated the joining quads and conditional lines would
be a big step forward. This could even be done in Excel - not that I am a
great advocate of Excel as a “programming language”.

| Thanks everyone for the advice. After posting last night I went ahead and changed the hat puff to a 1/8 segment and called it s/6898s18.dat. Any conditional lines falling along the x, z, x+z (diagonal), or x-z axes were moved into the main file to (...) (20 years ago, 26-Nov-04, to lugnet.cad.dat.parts, FTX)
