Hi,
I'm creating a 3d ramp and need to create one surface of the whole thing, but as its overlapping on certain areas the surface keeps attaching itself to the corridor below it and another corridor crossing over top.
any ideas how to create a smooth surface that doesnt connect to anything overlapping it?
Cheers
Ramps can be made quickly with a corridor, feature lines or a grading. It's tough to know what information you have and just what you need to do. A picture or dwg may help explain this problem better.

Is this like a flyover ramp or underpass structure? If it is then you might have to ensure that the featurelines used to create the two surfaces are on separate sites.
