Is there a way to delete subd vertices? Like collapse mesh vertices?
At the moment, workaround is insert point then delete the edge.
Shift+ctrl drag to select, It should let you delete it, does it not?
Nope never does. Just posting because I’ve ran it into enough times that I’m bored of it aha.
Whilst I’m on it… is there nothing yet for circle fitting? I thought we might have already had something like this. Align only seems to do the vertices rather than the smooth points, even if picked in smooth mode. Must be a basic misunderstanding of mine - that those picked smooth points aren’t like edit points.
Another niggly one…
If you have a face that straddles the symmetry line, gumball dragging to reshape will lose the selection. More reason to have an edge through the middle, sure, but just in case it hadn’t been noted.
Regarding matching to a circle: A work-around for this is to use Flow. Duplicate the border of your shape first, align start points of your circle to that shape, then select the points and flow.
Guess it depends on the geometry.
The normal behaviour seems to be that you can delete vertices.
Could you post your example?
PointsOn command (and F10 key) turns on SubD vertices (and control points). When they are turned on, they are easy to delete.
He’s talking about a point created using InsertPt. They really do not delete.

If you read my post, you will learn how to delete vertex made with the InsertPt command.
By the way, I have just discovered minor bug: when I paste the word PointsOn into the command prompt, Rhino returns error message: “Unknown command: InsertPt.” If I type the InsertPt into the command prompt, it works fine.
Ok, but that’s literally what I did in my video, and they do not not delete. Maybe we are running different versions of Rhino? I’m seeing same thing that Jonathan is seeing.
Rhino 7 SR1 2020-12-8
I am using the same version of Rhino: 7.1.20343.9491, 2020-12-08. I can easily turn on and delete all SubD vertices.
Hi @andrew.nowicki, I find that I can delete internal verts but not those lying on an outer border in Rhino 7.2.21005. Could you confirm that you can delete a vert on the border using F10, _delete?
Thanks

This may be a bug in Rhino 7.2. If you post this SubD model, I will try to delete this vertex using Rhino 7.1.
I didn’t keep that hackabout, but here’s another simple example that behaves the same:
SubDVertsDelete.3dm (35.1 KB)
I cannot delete any vertices located on the perimeter of this SubD surface. I tried to use RepairSubD command. Rhino said: “Inspected 1 SubD. No flaws detected.”

Hi @Jonathan_Hutchinson et al
I believe the command you are looking for is Stitch - select the vert you want to delete and then the vert you want to “pull” towards and then where to put the new, stitched vert. I don’t know why you can’t just delete it. Maybe @theoutside or one of the other sub-d brains know?

Hi all - thanks, I’ve added this to the heap. It looks like it may be a bookkeeping error, possibly - the wrong edge being deleted with the point. But the bigger brains will know…
RH-62254 SubD vertices cannot be deleted
-Pascal
Deleting points from the outside in those cases would also give you a split edge. So basically, deleteing the vertex doesn’t delete the vertex.
A bigger brain has probably done it this way for a good reason no doubt, I’m maybe just being picky.
Hello,
I have a similar problem. I am following SubD Chair tutorial (- YouTube). When I try to delete vertices like shown in 19:07 Rhino removes all points but 2.
Hello - it turns out this is by design - for now, to remove the vertex, delete the attached faces.
