I created a 3D topo from an imported DWG and can't figgure out how to draw site elements (like a road or property lines) and have them lay on the 3d topo instead of floating above or below it in 3d view. Any ideas?
Thanks!

to draw your property lines go to the site tab and pick the property line tool.
regarding roads and sidewalks, you can do 2 ways:
1. split your topo and assign different material
2. more complicated but more accurate, refer tutorial on complex slabs...

Thanks for the reply, but the property lines you refer to (as far as I understand) only appear on the 2d plan view. I would like to show the property lines on the 3d view.
Anyone ever do this?
Thanks

the only way to show the property line in 3D is to model it, just make a wall (thickness to suite) and pick your property lines...

I also imported a DWG into revet, this was to use the levels of the site and use the survey features which was contained in the DWG file. I have modeled the site and the trees onto my Revit topography, but would like to know how to 'bind' or 'attach' the dwg lines onto the Revit topo. The DWG lines are shown to be floating about the topo in the image which I have attached. Cheers Tim

Are your lines in the DWG in 3D??? you can control the level and the offset to position your lines but you CAN'T drapped the lines to the surface like CIVIL 3D does... I don't see any advantage to do that because the CAD file ONLY serve to guide you in your drawing, after that delete them...

You can still use the CAD lines in the plan as information, but there should be no need for this in a 3d view. You can use the lines as a guide to develop the 3d view as Typhoon suggests to create the different surfaces, such as roads and pavements.

Thanks both, I was interested in having the 2d lins which are from a AutoCad DWG be 'draped' over the 3d revit generated topo. However I understand this cannot be done, and I will continue to trace over the 2d lines onto the topo.

For 3D Property lines, here is an imperfect workaround I normally use: create a subregion (or as many as necessary) by tracing your property lines, making sure you form a closed loop(s). Change the material so that your subject property "pops" out from the surroundings in shaded or shaded w edges views. you'll need to create several if you want to diffrentiate between interior and exterior roadworks etc. If you want to show several adjacent lots create several subregions with a small ofset from the property lines so that subregions don't share edges (but appear to).
