Hi maysam,


Sub RunScript(ByVal arr_crv As List(Of OnCurve))

Dim arr_nc As New List (Of OnNurbsCurve)

For i As Int32=0 To arr_crv.Count - 1
Dim nurbsCrv As New OnNurbsCurve
arr_crv(i).GetNurbForm(nurbsCrv) 'convert OnCurve to OnNurbsCurve
arr_nc.Add(nurbsCrv)

Next

'create a untrimed surface from 2,3 or 4 edge
A = Rhutil.RhinoCreateEdgeSrf(arr_nc.ToArray())


End Sub

If your edge curves aren't planar, Marc Hopperman made a component for creating surfaces that uses the Rhino patch command.

Patch

Hi taz,

patch is not the same as surface from edge ;-) ...
why do you use the patch? surface from edge also works with not planar curves!

Good point... I was wrong about the planar part.

Using "patch" is just another option, which works with any number of curves...

hi o[U
Thank you for script. It’s very helpful.
But I thought I can easily use your script as base and modify it in order to replace with another command, but it didn’t work. Actually I want to run the Unroll Developable Surface command from rhino. Could you please help me with that?
Thank you

Hi maysam,

this is not that easy like surface from edge ;-)
take a look @ Marc Hoppermans scripts, he still shared a unroll surface script.

thanks to Marc

Hi I tried your solution in GH but it doesnt work
I pasted your code in a VB component and it turned grey, but the input curve makes no surface..
what I'm doing wrong?maybe the wrong type of curve?
please help
thanks

hi ivan

you have to check list and oncurve @ the input variable cause you need 4 curves and this is, as you can read from the script text , an array
