It took me a minute to grok what you were saying.  The 'test line' is
inaccurate for anything except joining one half-cylinder to another.

We could push the cylinder polygons into one file, the final edge-line into
another file, and reference both files from the current 2-4cyli.dat file.
That way, new parts could use the new un-delimited half-cylinder while
existing files continued without change.

Files which are currently broken will need to be updated, no matter what
else we do.

(...) Do you have a naming convention in mind for the new un-deliminated partial cylinder files and the joiner files? How about X-Ycylu.dat for un-deliminated partial cylinders, X-Ycyla.dat for the leading optional line, and X-Ycylb.dat for a (...) (25 years ago, 13-Mar-02, to lugnet.cad.dat.parts, lugnet.cad)

(...) I agree. I think the problem is that the current half cylinder primitives expect to be mated with other cylinder primitives to create a whole cylinder. Connect edge A with optional line to edge B without optional line. But connect edge A to (...) (25 years ago, 13-Mar-02, to lugnet.cad.dat.parts, lugnet.cad)
