This will hurt performance and of course, it would be better if you could use only 1 call per part. (...) You don't need to do that with LDraw files, (...)

In fact you can, use as many as you like, but that it's not the goal. if you read my previous mail, following this one I'am replying, you got the ideia that no WINDING meta command is the ideia, if the .DAT is well optimized. If someone want's (...) (25 years ago, 18-Oct-99, to lugnet.cad.dev)

Simply keep track of the state yourself and send either vertices 1,2,3 or 3,2,1. The part author can use as many (...) (25 years ago, 19-Oct-99, to lugnet.cad.dev)

Just minimize the use of the 0 CCW and 0 CW meta-commands, to boost performance. When optimizing existent or (...) (25 years ago, 20-Oct-99, to lugnet.cad.dev)
