I am working on a large park project. I have a proposed and existing surface. I have created a volume surface to show elevation banding with cut and fill ranges. I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas. They really want a boundary of hatch. What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.

Im looking for something a bit more quicker. There are hundreds of areas (pockets) of grading changes. That would take me days.

okay... Thanks... I'm on my way. What is the best way to extract these lines? Can I landxml out? explode the surface and wblock the lines out?

...Basically I want to generate a boundary polyline from the elevation analysis I see for all the cut areas...
Oh, I just did what you told me to do.... Extracted the Elevation solids from the elevation analysis and shrinkwrapped them with polylines...About 17 seconds from start to finish.
Oh..I would shrinkwrap those Fill areas first then to get polylines in there ...Right?
Are those areas of fill? You only want to illustrate areas of cut. Holes in fill areas would be nice, assuming my assumptions are valid.
The situation is this. We are re-grading an existing park. I told the volume surface to show elevation of -100 (which is way plenty) to elevation 0 with 1 band color. I was asked to create a drawing for a non-civil 3d user to see just the areas of cut. So yes, the areas of no color in my sample is fill areas. I believe the user would like a closed polyline around the interior shapes also for hatching purposes.
10-4...
If you do a range from 0 to +100 those holes fill with Solids, right?
Are we making headway?
Try to do this in under 60 seconds from start to finish:
-Wrap the Fill solids from your analysis, then:
-Wrap the Cut solids from the analysis.
