I am trying to build a portion of a highway for a rendering. I realize that Revit is it not the best way to do this, but there is no other option. The topography is modeled, and I am now trying to put the road in. My thought was to draw a 3D line that replicated the topography and then use that line as a path foe a sweep that used the profile of the road (in section). I am not able to snap to the topo and if I import the topo lines used to create the topo from AutoCAD, they are not useful either. Does anyone have any insight into how this should be approached?? Any help - please!!

Thak you - - and sorry for the delay in response. You will see in the two attached images, that the slope is vrey slight. I am trying to place a road on top of this that follows the slope exactly. I realize I can make subregions, but I am trying to model the road with the correct profile (see Topo - Road Section). I hope this makes it a little clearer.

Here is the road cross section profile I mentioned previously.

Have you tried using "sub region" and "split surface" under Site menu? then use "paint" bucket to change material of the area you want to change. It should work.

At this point, that is the path I am taking - adding the road cross section profile seems undo-able. Thanks.

Wise choice... but 3D paths you can do. Just not a good choice here.

Another option is to create the road using a floor, where you can have the correct plan shape and modify sub-elements to adjust the heights to follow your site slopes.
