3 Click (Element Properties).
4 In the Element Properties dialog, set Phase Created to a phase earlier than the view's phase.
For example, when the view's phase is New Construction, set the Phase Created value to Existing.
5 To create a graded region on the toposurface, do the following:
■ On the Site tab of the Design Bar, click Graded Region.
■ In the Graded Region dialog, click Select and Edit.
■ Select the toposurface.
This demolishes the original surface and creates a copy that occupies the same boundary as the
original.
6 Select the toposurface copy, and click (Element Properties).
Revit Architecture lists the new cut/fill properties for the toposurface.
NOTE You may need to press TAB to select the copied surface. You can apply a phase filter to the
view to see only new elements, and not demolished ones. See Phase Filters on page 1265.
Cut and Fill in a Schedule
You can create a topography schedule that includes cut, fill, and net cut/fill values. You should also name
the different surfaces to distinguish them in your schedule. For more information, see
Creating a Schedule
or Quantity on page 125.
Cut and Fill Reporting with Building Pads
If you add a building pad to a graded surface, you will see cut and fill reported separately for the pad and
the toposurface in a topography schedule. This is because the pad divides the graded surface into 2 surfaces:
one is the surface under the pad (the graded surface), and one is the surface that is not under the pad (the
pad surface).
You should name both the graded surface and the pad surface in order to distinguish them in your schedule.
To select the surface under the pad, press TAB to highlight it, or turn off the pad's visibility. (See Overriding
Visibility and Graphic Display of Individual Elements on page 151.)
Building Pads
You can add a building pad to a toposurface and then modify the pad's structure and depth. You add a
building pad by sketching a closed loop on a toposurface. After sketching the pad, you can specify a value
to control the height offset from the level and other properties. You can define openings in the pad by
sketching closed loops inside the perimeter of the building pad, and you can define a slope for the building
pad.
The following image shows a section view of a building pad offset from the surface.
