How to carve void out from landscape topography?

[Anonymous]

Hi All,

Please see attached, screenshot relating to the following issue.

Is there a way to "carve"out of Revit's landscape topography almost like a "cave"effect?

Thank you in advance.

Use building pad

(Massing & Site / Building Pad)

Something like this Tunnel? You can get there by Exporting a Toposurface to DWG and then Importing the DWG back it into a Mass sketch environment. Once you've got this Mass, you can apply a Floor (w/ Variable Thickness) to it's faces. The Floor would be the material of the earth. Once you've got the Floor by Mass Face in place (now resembling a Toposurface), you can cut through it, or out of it, using void cuts. To learn more about this technique, check out this Link: http://au.autodesk.com/au-online/classes-on-demand/class-catalog/2013/revit-for-architects/ab3340#ch...
