Creating an Autodesk Revit Building Pad

Posted on October 8, 2013 by Curt Egli, Synergis Building Solutions Engineer:

So now you’ve got a terrific building and you’ve got your site’s terrain modeled, and – consequently – you’ve got a grassy slope running through your building lobby.  This just won’t do!  That’s where the Revit building pad comes into play.  Even though you and I know the dirt should be retained at the exterior of a building’s wall, Revit doesn’t catch on to that.  You need to tell Revit where the boundary of your building is, so that it knows to cut a void out of the terrain.

The terrain is called a “Toposurface” in Revit, and an Autodesk Revit “Building Pad” will automatically cut through a toposurface.  Usually this cutting boundary follows an outline of your building’s basement walls or follows along a retaining wall.

I’ve broken the exploration of this process into two parts so you can take note of two different workflow situations.

The Part 1 video is the process when the building walls and the toposurface are in the same file.  (one .RVT file).

The Part 2 video is the process to follow when the building walls and the toposurface are in separate files that are linked together.  (two .RVT files that reference each other).
Let’s explore this together…

Part 1:

Part 2:
