here's one solution: linetype 6 can be used multiple times in a row, with the
x, y, and z set to where the curve must pass through, and the orientation to
what the tube must look like in that position.
hey, it *MIGHT* work.
another, MUCH easier way would be to use THREE new linetypes:
6, for the beginning orientation + position [same format]
7, for the beginning of any changes in angle/position during the curve itself
(to avoid intersecting something else, for instance)
8, for the end of that point,
and 9, for the final position + orientation
7 could also be used as a line-must-pass-through-here-in-this-direction kind of
thing, and 8 would be omitted
any better?
