Extend Curved Surface

Hello All,

I am looking to extend a curved surface so that I trim it to make a poly surface with the original loft.

Simply put...the extend surface tool in rhino.

Does anyone have insight into this...

Attached are 2 screen shots. The black surface is the "extendsurface" command from rhino, and is what I'm looking to achieve.

Would it be useful too have a simple vb script to plug the surface into?

Any help is appriciated.

Thanks,

A good question. It`s a pity no one ever answered it.

I achieved the extend surface function by utilizing Python (not an expert at python, though). Here's the code I used:

import Rhino as rc

if Cycle_Sides == 0:
Selected_Srf_Side = rc.Geometry.IsoStatus.North
elif Cycle_Sides == 1:
Selected_Srf_Side = rc.Geometry.IsoStatus.South
elif Cycle_Sides == 2:
Selected_Srf_Side = rc.Geometry.IsoStatus.East
elif Cycle_Sides == 3:
Selected_Srf_Side = rc.Geometry.IsoStatus.West
else:
print "Error, dude!"

extended_srf = Original_Srf.Extend(Selected_Srf_Side, Length, True)
