Tweak the handles to make more space in the request ID, so that I 

can use the high bits as an "import ID" for imported parts, for
hierarchy (that retains parametric capabilities).

Implement enought that I can draw a datum point or a line segment,
and drag points around in three-space. Still so much to do.
