I already asked for this, here: "Straightening" quads
We are finding that modeling SubDs in Rhino is great if you compare it to not modeling with SubDs at all in term of productivity, but it’s an absolute nightmare if you are used to be fast, efficient and productive.
BTW the example I posted was from a custom script in Modo (from Seneca Menard I believe), I think it would be great to see more selection tools muscle and development tools in RhinoCommon so people can make these ‘nerd AF’ tools for Rhino. I totally get it that building all these modeling tools internally for McNeel will take years (if it ever happens), so we need street-versions of them for now.
