Thanks Benson, Problem solved.

Hi all, I need to create a surface and give it volume to try do some earthworks calculations. I have imported the data in a series of 3d polygons into VW and have tried to convert to NURBS curves and a few other things but keep getting errors when it comes to creating the actual surface. I typically used VW for structural drafting and a some 3d modelling so I'm a bit out my depth. Any help would be greatly appreciated Tin extraction.vwx
