Chris, When I display this DAT file in MLCAD, I get a couple of "bowties". I took the liberty of finding the errant lines and finding a solution for them. 0 4 6 15 7 -10 18.72 6.03 -10 14.93 15.68 -10 12 14 -10 4 6 18.72 6.03 -10 15 7 -10 14.93 (...)

(...) So it's obvious what I copied from one part to the other, huh! Thanks for making the fixes - I'll make sure the revised versions go in for the voting. Chris (25 years ago, 6-Apr-00, to lugnet.cad.dat.parts)
