What is an optional line? These seem to be used for modeling curves, but I don't have a clue how to use them. While I'm asking, what is a BFC statement? Um... and why does MLCAD use a German-localized cancel button for the BFC statement dialog? -- (...) (24 years ago, 10-Jan-01, to lugnet.cad.dat.parts)

(Note: Please follow-up to ".cad.dev".) (...) OK, first you need to bear in mind that LDraw does _NOT_ draw true curves, it draws _angles_. If you have enough angles in a line, from a sufficient distance, this angled line will _appear_ to be a true (...) (24 years ago, 10-Jan-01, to lugnet.cad.dat.parts, lugnet.cad.dev)

(...) See (URL), question 20, linetype 5. Basically, if you're modeling a curved surface, and as part of the model, you've got two adjacent triangles, ABC and ABD: A /|\ C | D \|/ B The common edge, AB, needs to be modeled as a conditional line.

Thanks everyone for your helpful information. I believe that I can now properly model curves manually (as opposed to just using cylinder primitives). I'll be trying it out on the "coarse" version of the Duplo bottom stud. As for BFC statements, I (...) (24 years ago, 10-Jan-01, to lugnet.cad.dev)

I could make a tool to display a part (wireframe view) from any angle. Clicking on a polygon command in the DAT source (displayed below the view pane) would cause the edges of that polygon to appear as arrows, showing the order they were defined in. (...)
