Rebuild cutted surface

Rhino Developer

Hi everyone,I know there is a “Rebuild” function in rhino that can reassign the edited surfaces to control points,
bB aA

But in RhinoCommand I have tried,
_nurbssurface = surface.Rebuild(uDegree, vDegree, uPointCount, PointCount); doc.Objects.AddSurface(_nurbssurface);
It always shows me the deleted part.

Is there any other way to solve this problem to achieve my goal?

i am not sure i understand, are you scripting something? in any case there should be a Retrim option, in the command and hopefully also for scripting it. and by the way its cut, cut cut :smiley: not cutted.

I guess you’re looking for Brep.CreateTrimmedSurface:

import Rhino
from scriptcontext import doc
def RebuildTrimmedSrf():
    filter = Rhino.DocObjects.ObjectType.Surface
    rc, objref = Rhino.Input.RhinoGet.GetOneObject("Select surface to rebuild", False, filter)
    if not objref or rc != Rhino.Commands.Result.Success: return rc
    brep = objref.Brep()
    if not brep: return Rhino.Commands.Result.Failure
    face = brep.Faces[0];
    rebuilt = face.ToNurbsSurface().Rebuild(3, 3, 10, 10)
    rebuilt = Rhino.Geometry.Brep.CreateTrimmedSurface(face, rebuilt, 0.01)
    doc.Objects.AddBrep(rebuilt)
    doc.Views.Redraw()
    return Rhino.Commands.Result.Success
if __name__=="__main__":
    RebuildTrimmedSrf()
