Hi Mark,
My two questions are:
1. How would behave the original LDraw program regarding this proposed
extension?

| Time to throw fuel on the fire. Why are we still latching ourselves on to the original dos LDRAW program. Isn't it time the LDraw community graduated to Windows/Mac based programs and let the DOS program fade away from usage. Much like other (...) (23 years ago, 7-May-02, to lugnet.cad.dev)
