Finding topography of a ground surface and exporting it to revit in 3d

[shershahbacha9]

Hello Respected experienced people !!

I need to know about finding topography of a ground surface (help from google earth or any other ) and exporting it to Revit to make it 3D there , so that we could know the cut and fill according to our desire .

1)  It would be highly appreciated if you could show me all possibilities as i want to know all possibilities by which i can do my task as i have to do comparison in the end. 

2) Also it will be good if you could suggest me some good material , links or papers to read for it and have a broad idea.

Hi @shershahbacha9 

There are a couple of workflows in this forum post.

What version of Revit are you using? If 2018, I would highly recommend CADtoEarth.  Unfortunately, not available for 2019 or 2020, but you can create the Toposurface in 2018 using the add-in, and then upgrade the RVT to 2019 or 2020.

Use your Previous Version Rights. You are allowed to use 3 versions.  Download and install 2018 and then install the free CADtoEarth Add-in from the Store.  I would if I were you.
