Hi,

I’m looking for a way to transform curves from WorldXYZ to a Surface’s UVN

i.e. script the ApplyCrv command

I’m scripting in Python and have not found anything yet in RhinoCommon. I try and dig deeper while waiting for someone to chime in here.

I have found a solution that seems to be what ApplyCrv does:

```
# bbox is boundingbox from all iso_curves (these need to be morphed)
Uplane_interval = Rhino.Geometry.Interval(bbox.Min[0], bbox.Max[0])
Vplane_interval = Rhino.Geometry.Interval(bbox.Min[1], bbox.Max[1])
# create a planar surface on XY plane around geometry to be morphed
from_surface = Rhino.Geometry.PlaneSurface(Rhino.Geometry.Plane.WorldXY, Uplane_interval, Vplane_interval)
# create SporphSpaceMorph instance (who's been drinking while making up these names?)
# to_surface is NurbsSurface to 'Apply the curves to'
Morph = Rhino.Geometry.Morphs.SporphSpaceMorph(from_surface,to_surface)
# Morph the geometry one by one
for crv in iso_curves:
Morph.Morph(crv)
```

Thanks
