Lars,

Awesome.  I tip my hat to you and Lutz.  :-,

I don't mean to complain, in fact I am currently trying to figure out a
solution anyways, but I thought I'd raise these issues and see if anyone
else has figured it out already.  Basically, some LGEO pieces are not
directly compatable with the LDraw parts library and need some tweaking to
come across properly after L3P-ing.

The inconsistencies I have found so far:

<part:3149> hinge 2x5 base in LDraw becomes <part:3145> tipper end after
l3p+lgeo

<part:3942> cone 2x2 becomes <part:3943> cone 4x4 afterwards, as well.
Renaming lg_3942.inc to lg_3943.inc doesn't work btw

Are you sure you have got ALL updates installed properly?
My L2P_ELMT.TAB is from 31-12-99 and the latest part is
lg_3873.inc from 23-09-99.

BTW, you can use the -d option to L3P to see the contents of LGEO's
*.TAB files: "l3p -d -lgeo somefile.dat | more"

<part:4588> brick 1x1 round with fins doesn't exist in clear in lgeo, so
there's some parsing problems with the POV file...weird

Yes, Lutz forgot the lg_4588_clear in that file...

<part:6536> technic axle joiner perpendicular ends up rotated 90 degrees on
the part's y axis after l3p+lgeo

It's fairly easy to fix these by hand in the POV file, but I'm not so sure
how to fix the overall situation.  Changing either the LGEO library or the
LDraw parts library would most certainly break existing models, and
requiring L3P to handle these on a piece-by-piece basis would get to become
a headache for Lars.  Unfortunately, the latter is the best solution I can
think of so far.

L3P already has one exception: it adds a missing texture
"texture {lg_black}" to pattern lp_0008.inc used in lg_3626p01,
the Minifig Head with Standard Grin Pattern :-)
But, that's not the way to go...

Actually, another possibility is for L3P to incorporate some kind of
external lookup table, in a file which can be maintained separately from the
L3P binary.  Perhaps a simple mapping from LDraw to LGEO with part number
changes and translation matrix -- any parts not mentioned in the table would
just go through as they do now, which would keep the table down to a
managable size.

No, Lutz Uhlmann should be alerted and fix his files. Otherwise also L2P
would suffer from the same mistakes...

I also have a list of errors:
lg_0711.inc: "#declare lg_0709_clear" should be "#declare lg_0711_clear"
lg_6081.inc lacks lg_6081_clear
wrong offset in z  lg_6832.inc  Windscreen  4 x  4 x  1
lp_0008.inc: missing "texture {lg_black}"
lg_cyan, lg_tan, lg_orange, lg_clear_brown, lg_clear_neon_orange are
missing in L2P_COLR.TAB

Lutz should also consider making a new version of L2P_ELMT.TAB,
preferably in text rather than binary.
The current format is inadequate for a conversion table between
DAT filenames and LGEO filenames: He only uses an integer for the
DAT file number (again, try: "l3p -d -lgeo somefile.dat"), which cannot
handle all our letter suffixes properly.
But I've already suggested that to him long ago...

Anyway, I love the changes you've made to L3P Lars; incorporating Lutz's
LGEO parts has really spiffed up my microfig collection.  :-,

Thanks.
/Lars

(...) Huh. I downloaded the complete set, but my L2P_ELMT.TAB is from 25-1-1999. The other timestamp is off too. I figured this could be an old LGEO install, but I tried again on a fresh machine and I still have the older files. Exactly which file (...) (23 years ago, 23-Feb-01, to lugnet.cad, lugnet.cad.dev)
