I just realized the 1-4con3.dat and 1-4con4.dat don't have optional lines in them. Is there a reason for this, or is it just an oversight? -John Van (25 years ago, 10-May-99, to lugnet.cad.dev)

(...) That's odd -- my copy of 1-4con3.dat does have optional lines, but 1-4con4.dat doesn't. I'll send Terry fresh copies of both. Steve (25 years ago, 11-May-99, to lugnet.cad.dev)

(...) Hmm, I'm using the cone primitives in 30384... How do the cone primitives work? The geometry of the canopy doesn't match either the con3 or the con4 primitive... right now I am scaling 1-4con4 to create part of the half-cone, and then using it (...)

Optional lines should actually be called "conditional lines." They are used to model rounded surfaces so that the edge-lines only appear if they form the outer boundary of the rounded surface. If you think of a cylinder, you want edge-lines to show (...) (25 years ago, 11-May-99, to lugnet.cad.dev)

(...) What does the numeral at the end of the name signify? (1-4con'3') If I make a cone that matches the slop I need for the canopy, how would I determine what to call it? --Karim (25 years ago, 12-May-99, to lugnet.cad.dev)
