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
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.
