Autodesk labs site provide "Google Earth TM Extension"for AutoCAD, Architecture, Civil 3D, Map 3D, the usages of the tool are:
- Import Google Earth image to .dwg applications (AutoCAD, Architecture, Civil 3D, Map 3D)
- Publishing 3D DWG Models to Google Earth TM
- AutoCAD Drape a grayscale Google Earth TM image onto a 3D mesh in AutoCAD applications
The 3rd function provide a method to import the elevation data for the current Google Earth view into AutoCAD as a mesh, then one can link the site .dwg as a reference to create Revit site, here are the steps:
- Launch AutoCAD (or Civil 3D, etc), do as per the guide (please refer to page 8-11 of the Google Earth TM Extension white paper, shown at the bottom of this article) indicates. Here are the results,
- Launch Revit application or open a Revit project file (.rvt), link and put the .dwg object onto the target level, adjust the location, size (scale factor) if necessary.
-
Activate the Mass & Site tap, create "Toposurface"
-
Choose "create from import\select import instance" option and select the linked dwg file.
- Here is the result in Revit GUI,

It's a shame you need to use Autocad to get the toposurface into Revit

I love the blog, but this issue about Create Revit Site with Google Earth Surface is great. It is very useful for a job that I have to present next month. Thanks again. Great work

When I import de DWG on to Revit it looks OK when I create a “Topsurface” and select “create from import\select import instance” icon, it dose not let me select the linked dwg file.
Is there something I’m doing wrong?
