I am using R8.1 and have created a topography schedule that I want to use to calculate cut/fill.

I created the topography with the Phase Created: Existing and Phased Demolished: None.

I created a pad with Phase Created: New Construction and Phased Demolished None.

I made the cut/fill portion of the topography with Phase Created: Existing and Phase Demolished: New Construction.

I have changed the View Properties with Phase Filter: Show Previous + New and Phase: New Construction

The Topography Schedule is set up to show: Name, Projected Area, Surface Area, Cut, Fill, and Net cut/fill. The columns: Cut, Fill, and Net cut/fill indicate a value of 0 (and my cut fill should be significant). The other columns seem to be working correctly.

 Any suggestions why the Cut & Fill are not working in the schedule would be much appreciated.

After working on this issue more I found a solution that appears to be working. The basic problem I had was that I was not using the Graded Region function. Here is what I found (all steps may not be necessary, but the end result looks correct):

1.Link the dwg topo file in the view Floor Plan: Site Plan

2. Create a Toposurface then place the created topo on Phase: Existing and Name the Element "Existing Topo"

3. Create a Graded Region (select copy internal points) hit Select and pick the topo surface. This will create a duplicate topo, name this topo "Proposed Topo"

4. Set the Phase Filter to: Show New in the View Properties dialog box.

5. Add the required Pads on the correct floor plan

This is a brief description of the process that appears to work. I guess I have to just trust the numbers that show up in the schedule, a little reassurance in their accuracy would make me feel better. If anyone has a better way to do this I would be interested in hearing about it.
