Hello,
I am working in Civil 3D 2012. I created a grid volume surface based on two other surfaces I have in my drawing. One of the surfaces is extremely large and re-building the volume surface takes an extremely long time, i'm assuming because it's calculating every point of the large surface, even though my comparison surface only covers a fraction of it. I want to add a boundary to the surface so it doesn't have to go through the entire large surface, however when I add an outer boundary to the volume surface, all of the information disappears, as if it excludes the information. When use the same boundary but make it a "show" boundary it works, however it's still going through and calculating all the points on the large surface.
I don't want to do a bounded volume under the analysis tab because I need an acutal surface to work with and apply styles to for further design. Applying a boundy to my comparison surface didn't do it, and I can't add the boundary to the large surface because I need it to compare other surfaces i will create in different areas (also it's only a data reference in this drawing.)
Does anyone know why the "outer" boundary isn't working? (i'm using a simple polyline for the boundary) Does it need a special sort of object for volume boundaries?
Any help?! thanks!!
