Filed as InsertPoint support for subd https://mcneel.myjetbrains.com/youtrack/issue/RH-53954 an alias called Knife may be needed here (I asked for the same initially) but I think the functionality will be the same. Try it on a mesh now to test. Subd edges have mid snaps too which differs from mesh edges currently so it will be easy to cut the face evenly once InsertPoint works on subd.
Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-53823 for planar, I’ll add your vote for radial as well.
Can you give me some more info on what you want here? Look at CollapseMeshVertex and CollapseMeshEdge on meshes now. Is this what you want on a subd? It tends to make lots of tris which is why I’m asking. Also see if Ctrl + Shift select / sub-object select > Delete of subd verts and edges is of use for comparison to a traditional collapse in mesh modeling. I’ll file what we need but want to make sure I get it right.
Weld works on subd edges and verts now using WeldEdge or RemoveCrease which is on the Subd toolbar. The counterparts would be UnweldEdge or Crease. I think this is what you want, let me know if not.
Does the Filter menu > sub-objects let you do what you’re after? Also try the Named Selections panel to save selections of faces, edges, ctrl pts etc.
I think this is the guide curve Bridge enhancement but also see the present method using sweeps above.
I think you’re looking for subd Split support essentially with a Slice tool. I filed https://mcneel.myjetbrains.com/youtrack/issue/RH-54108

Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-49860 for InsertEdge subd support and https://mcneel.myjetbrains.com/youtrack/issue/RH-51194 for sub-object subdivision. You can also try Inset now on a subd face for adding one face in the center on another.
Filed as https://mcneel.myjetbrains.com/youtrack/issue/RH-54110 . Use a sub-d friendly curve (option in Curve command) and then ToSubd on the result of RailRevolve ought to work in the meantime.
Pipe has subd support already, if you mean multiple pipe intersections this is something that is being discussed and experimented with. You can use the Dendro add-on for GH now to make voxels and then QuadRemesh that to get to subd.
There are some components now for making subd from mesh or extracting the control polygon from a subd to get a mesh. Not a lot else right now but I’m sure more will come. FYI @DavidRutten
If possible, can you please make separate posts about individual features you need or want changed? This will help developers make sense of the thread and understand the key points when they reference the discussion later. Thanks!
