FIrst time using CIvil3D to figure volumes. I have a very large aerial topo from a couple years ago to compare against a topographical survey I completed this year. No problem creating surfaces.
Question: In the topo's, I need to get a volume from two different areas....one area being a fill area, the other being the borrow area. Don't want any volume data throughout the rest of the site.
Do I just create one large surface for each topo and designate boundaries somehow? Or do I need to create multiple surfaces for each topo? If this is the case, will I need to make sure any breaklines, etc. don't cross from one area to the other?
Any help would be appreciated...
Either method will work, but for simplicity I would just create two surfaces and then use the bounded volume tools to compare them in the two areas you're interested in.
What version are you using?
I am using 2012.
So you are saying to just create one surface for each topo, then use the 'bounded volume' tool to figure volumes for areas that I want to compare?
Ok....just looked up 'bounded volume'...appears like that should be easy method.
I'd create a volume surface and use that - you will also be able to scrutinise it to identify the location of the cuts and fills
