I have my site contours as polylines with elevations. When imported into Revit, they just behave in a weird manner. I seem to loose some arcs. Are there any limitations that polylines have when they are imported. Please try with the attached file.

mate, I have tried your file and it works fine.
do you "use imported" when you bring it in? I have attached the file, I used meters as my units, don't know if this is right though...

I wouldn't import any ACAD linework into Revit. For the site, it is best to create a Revit toposurface using the "linked" ACAD file. I believe there is a decent explanation in the Revit help/tutorials.

 I assume this is what he was trying to do... that's what I did with the file anyway. lol

Thanks. But, your Revit file seems to have the same problem as mine if you compare the contours to the 2D in AutoCAD.

The Revit site tools are for visual representation of the model for presentation and rendering purposes. Revit is not a civil engineering package and I wouldn't even attempt to show any site work in Revit beyond the conceptual stuff. Sometimes ACAD has its place and accurate site drawings is one of them.

Contours lines can generally be located in numerous locations and still represent the same topography. In AutoCAD you specify where you want your contours to go. In revit, you plan out the topography and revit places the contours where it thinks they should go.
I'd trust that they still represent the same topography...
HTH.

Sorry about waking up an old thread, but exactly how do you create the toposurface to follow the dwg? You import the dwg. Go to toposurface...and then? Probably a dumb question but im very new at topo.

Importing a topo surface or creating a topo surface are both explained clearly in your help. Look using "site" as your search. "Creating a Toposurface from Imported 3D Data" will explain how to use a CAD file that has 3d points or 3d polylines.
