Create surface from contours

rhino query.3dm (33.5 KB)


Hi I am unable to use patch command to create a surface form the given contours. Is there any other way to achieve this? Thanks
Red= 0.0 meter
Blue= 0.0 meter
Magenta= 0.3 meter
Black= 0.7 meter

move the curves to the origin center, patch will then work as expected. your geometry is pretty far out, also patch generally works better when the input geometry is in the center keep that in mind.

in case you do not know that trick, if you have gumball turned on, select all curves and drag the center a bit keep dragged and type 0 and hit space or enter. it will then beam it to the center. then use select all and zoom to selected.

Hi -

I would use the MeshPatch command on this input. Either directly on the curves or extract the points and then run the command on the points.
You can QuadRemesh the resulting mesh and convert to SubD and then to NURBS if that is required.

that indeed gives a nice result. and also works on location.

used without converting to SubD.
