I have a building that I've modeled and am now attempting to include the site info. Our standard is to use 100'-0" as the main floor level. Our site topography is around the 6700'-0" range. The CAD site survey doesn't have 3d info, but uses crosshairs and text labels to indicate topo. I've already linked the survey file into my model so that the building is placed correctly and I have setup true north and project north. I have also already created property lines and other site info into the model. I have created site topography from the points in the survey, but obviously the topo surface is at the 6700' range. Short of doing a lot of math to subtract the appropriate dimension to each point to bring the sea level elevation to the building elevation, is there a simple solution to this issue? Or, as all other posts seem to indicate, is this a major letdown of Revit?

I would love to have my building intersect my topography, while at the same time have the ability to edit my topography, all while showing our 100'0" level elevation. The project is just a small house, not a big campus, so the idea of using a seperate site plan and building model seems excessive and time consuming.

I'm not totally opposed to just creating the topo as I have and moving it down to the the model, but I can't see the topo surface in any elevation views. I can see it in the 3D view, but not the elevations. 

I know this topic has been addressed in the past, and I've tried some of the proposed solutions, with no luck. If anyone has a good idea or good link to check out that would be great. I'm hoping that since people have had issues with this part of Revit for a while, that maybe they've fixed something in the latest version?

Hey there, 

I'm coming into this discussion a little late but just the same using RAC 2008 and realizing, although not wanting to believe, the lack of site options available.  

I'm wondering if you've since come across any solutions or good workarounds for this problem?

The one that I'm thinking of using is to just move the entire project up to the elevation that it is and cropping and dealing with all of the other tediousness involved with that approach.  

What unforseen issues should I consider when doing this? 

.....And, are there any site "pad" or "road' surface tools that can slope, let alone adequately represent a typical driveway condition? 

thanks,

will
