Hi, I am attempting to modify the coordinates of a subd vertex using python. I thought that editing the vertex ControlNetPoint would work (docs say it has both a setter and getter), but the subd does not change. Am I doing something wrong? Code posted below. Also, it would great to be able to edit…

I think this is not possible, but you can work with Grips or work with the control mesh instead, move the vertices, convert to subd and delete the old subd.

vert.ControlNetPoint.X = 30.0 gets the value of the control point location (copies it to a temporary Point3d) and sets the X property of that value to 30. For this to work like you want, SubDVertex.ControlNetPoint would need to be able to deal with a reference to the control point; I don’t think we …

Thanks Pierre. That does indeed modify the coordinates. Importantly I was missing Rhino.RhinoDoc.ActiveDoc.Objects.AddSubD(subd) because I thought I could modify the subd inplace without creating a copy. Looking forward to being able to modify the surface point locations directly. Cheers, Michae…

Hi, One year later, is still impossible to modify vertices (subd point) with Python directly? What’s about Rhino8? Thanks

Hi @Pierrafee , Sorry this thread got forgotten. There is a C# sample available to modify edit points in a SubD: mcneel/rhino-developer-samples/blob/dba9efe1b3dd4399f308d370aea2ed0f6622cfd8/rhinocommon/cs/SampleCsCommands/SampleCsSubDEditPts.cs using Rhino; using Rhino.Commands; u…
