I forgot to mention:  if anyone is interested in looking at the most-recent
version of the BFC proposal, it's still at:
<http://www.geocities.com/partsref/bfcspecv4.txt>.  The first screen of text
is meta-comments about the status of the proposal.  The actual proposal
starts at the line "LDraw Language Extension for Clipping".

  Re: BFC revisited
 
I have printed the bfcspec file for review. Hopefully I will get a response back to you. I have been using BFC in most all my new parts for the last six months or so.

I didn't straighten out all the primitives, but I did a number of them. I (...) (25 years ago, 17-Aug-01, to lugnet.cad.dev)
