Thank you for your kind reply, RNDPIS.
I do know how to do that, I was looking for how to import actual USGS data not having surveyor data, just for early draft purposes. I could not get the USGS data in a format that Revit could use (it may be possible, but I was not able to locate a supported file type on the USGS interactive elevation download site. AutoCad will provide some conversions but I don't have the AutoCad suite). So I kept looking for a way to get some actual elevation data to work with. Google Earth is less accurate than USGS so they say, but still, it is actual data which what was needed.
I found a great YouTube video that shows how to use the free SketchUp application to import Google Earth rectangle, or meshed multiple rectangles elevation data with image layer. Command is File > Geo-location> add location which will allow you to find a specific location on Google Earth. You can then bring the file into Revit. Rhino not needed even though the presenter uses Rhino in the YouTube. Took me two minutes.
