I'm not sure what you mean by "arctan(32/2) degrees". The arctan() function
doesn't give an angle as a result, does it? Anyway, I don't have one of thoese
pieces handy, so I'm not sure what the curve looks like. If it's less than 1/4
of a circle, I'd use the 1-4edge.dat primitive, shape it to fit correctly
(ignoring the excess) inline it, and remove everything not needed.

Again, without looking at the piece in question, I'd use one of the cylinder
primitives. Depending on how deep a curve you need, you could use the
1-4cyli.dat, 3-8cyli.dat, or 2-4cyli.dat. Just rotate the primitive onto its
side, turn it so the straight edges are even, and modify the Y components to
flatten the curve.
One example of this approach is the 1x2 log brick, 30136.dat. The sidewalls of
the brick are made out of flattened 1-4cyli.dat pieces.

No, but I'd recommend putting lines and conditional lines before the polygons
which touch them.
Generally, I put lines in the following order. Probably not an entire large
file, but within each section of the part.
1 - lines, conditional lines and edge-only subfile references.
2 - subfiles which contain both lines and surfaces.
3 - polygons and subfiles which contain only surfaces.

| Hi all, I've gotten pretty far on my first part (if you can think of a better name, please tell). However, as this is my firts part, I would like people to critique what I have done so far. The only part I haven't finished is where the seats curve (...) (25 years ago, 21-Apr-00, to lugnet.cad.dat.parts)
