Where to find and download maps for toposurface...

[#2]

Hello and welcome tot he discussion!

So a little more information would be helpful - 

You can create a toposurface in revit a few ways.

If you have an autoCAD dwg that has all of the x,y,z coordinate that can be used to make a toposurface.

If you have a point file from a surveyor - that can be used to create a toposurface.

Or - you can create it by placing points at a specific elevation.

As for downloading a map - I do not know of that feature.

I hope this helps!
