I have to create a road in Revit which runs up to the building at a slope. This requires some cut and fill in the revit toposurface to make the site conform to the road slope. So far the only way i've found is to manipulate the existing toposurface to approximately match the slope However this is very painstaking and difficult esp if the site is very huge. Any other alternatives?
one word: pads!
pads act as a device to create virtual "holes" in your topo (ex. underneath the building, roads, ramps, etc.). then you do your ramp as a separate object to cover this hole.
the beauty of it is that it does not affect your topo - if the road changes or goes away, get rid of the pad and the original topo seeps through unchanged.
but i would define it with a interpolate curve spline then extrude it solid and subtract that part from your terrain model, then fill in the void with a road you model, that water would drain off. import merge where ever you need.
Revit has pads, grading, and split surface within the toposurface tool. For an architects amount of detail it works well. If you are a civil engineer or surveyor and need it to be at a certain standard than I would suggest using something like Civil3D and bring it into Revit.
Check out these post from my blog for some toposurface info:
If you are looking for something simple to just represent a road then yes the split surface topography tool is your best bet, you will have to use the paintbucket tool to change the material there.
If your road surface is sloping at a constant grade, then try a PAD and a ramp infill.
If you have 2010 you should try linking in your main model and then using the conceptual mass tool to create a lofted road. There you can get some more complex shapes.
FYI, The Rhino import is format accepted by Revit is .SAT
the thing is that the toposurface generated from a surveyed cad file puts out thousands of points. which makes the surface too difficult to handle and to even adjust. You cant really make the toposurface join up well with the road surface in that case.

do not manipulate the original topo as you may end up doing that forever as the design changes.
Split surface works well. Then change the road surface to asphalt.
import it from Rhinoceros to save yourself sub par and stress
Hey Antisthenes. How do you do that from rhino?
what information about the site do you have? about the road, curbs etc.
