In P or MODELS.
Or inlined in your model DAT file.
Or included in your model MPD file.
If seams are not desired at all use -sw0.0001
see http://home16.inet.tele.dk/hassing/l3p_sw.html
I'm a bit uncertain what you mean by SUBparts. I would call the
DAT files in PARTS for parts, and those in PARTS\S for subparts.
L3P/L3Lab does not make seams for subparts, as the seams will be
made for the part referencing the subpart. Also parts referenced
by other parts will not have seams (a right wing referencing a
mirrored left wing should not have seams twice).
A model using two wings will have two references to the left wing,
one with seams (referenced by the model) and one without
(referenced by the right wing).
The simple rule I use is:
A reference to a DAT file will be made using seams,
only if all of these conditions are fulfilled:
1) The DAT file is found in PARTS [1]
2) The DAT file referencing it is NOT from PARTS
3) The determinant of the reference matrix is +1 or -1 [2]
/Lars
[1] The "file" S\973s01.dat is considered being from PARTS.
The backslash is treated as part of the filename, as LEdit/LDraw
don't know the S subdirectory.
If you reference 973s01.dat, it will NOT be found!
[2] This third condition will be added to the coming L3P/L3Lab,
