-It would be nice to be able to group and name sets of control points
That isn’t currently possible since Control points don’t exist as part of the curve/surface definition. Like “Edit points” they are cooked up at the time of editing so they do not persist after the points are turned off.
Hi Cairn- in the meantime, in case it helps, there is a plug-in here-
called SelectionSets (Bottom of the page) which does allow saving and naming recalling and combining and all types of probably marginally useful operations with both object and control point selections (can’t mix them). I confess I have not tested this in a while, but I think it works pretty well.
Thanks I’ll give it a try
