Sorry, i don't know who pneaster is, but he did put a hold on some primitives for differences in values. One of the primitives involved is 4-4con7.dat (...) I would like to know how these values are to be calculated (and who calculated the correct (...) (21 years ago, 11-Jun-03, to lugnet.cad)

(...) Sounds good. Make sure your generator is using spaces and not tabs. I have not checked to see how the original Ldraw responds to tabs as number seperators. Paul (21 years ago, 11-Jun-03, to lugnet.cad)
