pick 1st vert, rhino indexes automatically to the 2nd pick prompt- (no enter necessary)
pick 2nd vert-
enter to average verts, (done)
OR
slide to pick any location between 1st and 2nd
OR
pick first or second in the command line-
this behavior need to be added to full edge loops as well.
For partial loops, you will have to pick the 1st loop, then enter to index to the 2nd partial loop then enter to average, slide to pick location, or choose 1st or 2nd from command line.
you can also now select several verts, hit stitch, and they will collapse to a singularity.
you can also prepick verts, edge loops, or partial edge loops, then run stitch and enter to average. (need to add 1st, 2nd prompts to command line)
wait, wait, wait… just to make sure, we are allowing to work with more than 2 vertices here, Right?
I think the right thing is talking about first and last, not first and second. Here’s a very common thing of merging to last that happens a lot in subD modeling:
merging 3 vets to last, or merging 9 verts to last:
