Okay, I will add them back in. This will also make them unnecessarry for the

(...) I'm not sure I understand why they'd be unnecessary for the larger versions. I thought the idea was that ALL these primitives would have type 5 lines at the edges, but they would be extended in the tangent plane and thus only do half the job, (...)

(...) FWIW I also like the new one better. (...) I agree. The type 5 lines from the edges belong in the file. See here for my convoluted and poorly written reasoning. (URL) (25 years ago, 7-May-02, to lugnet.cad.dat.parts.primitives)
