When trying to create this shape like a road intersection, with one part sloped there doesn't seem to be an obvious tool that will create a surface because it is not flat so planar or extrude won't work but it is essentially a rather simple surface. I would probably split it up into smaller sections and use network but it seems a bit long winded for what seems like a simple job. Is this a short comming of most NURBS software or is it just MOI hasn't got this capability yet?.....or am i just being stupid and missing something obvious?!!

Cheers
