What is a "neutral" face?
How do I fix a part that is the wrong color?
(2021-06-10, 1:39)Travis Cobbs Wrote: Parts should be (mostly) all green. Any red is a sign of a BFC error. Any blue is geometry that is not considered by LDView to be BFC-capable. (This geometry has both sides drawn in normal BFC mode.) Fixing parts with red requires understanding of the BFC spec, and manually editing the part file to correct whatever is causing the geometry to be BFC flipped.

(2021-06-10, 3:26)Travis Cobbs Wrote: In LDView, in order for BFC to activate, a file must be identified as being a part (via a header comment or due to the fact that it is in one of the LDraw parts directories), and it must have a 0 BFC CERTIFY line. If you just want to turn off BFC for the part, delete the BFC CERTIFY line.

Does it come after the rotation center and rotation config? I.e.,
0 Arch 1 x 5 x 4 (Simplified)
0 ROTATION CENTER 0 0 0 1 "Custom"
0 ROTATION CONFIG 0 0
0 BFC CERTIFY CCW
(2021-06-10, 17:09)Travis Cobbs Wrote: The BFC CERTIFY line must be before any geometry line in the file. As far as I know, that's the only requirement for it. Line types 1-5 all count as geometry lines. Having said that, I don't know the rules for the header as a whole. If you plan to submit a file to the parts tracker, you'll have to learn those rules yourself.
