For quite a few years, we have been able to compare two surfaces (existing and proposed, for instance) and get some cut and fill values. Volume Dashboard takes it a step further because it allows you to break down your surfaces in phases or for some particular area of your concern such as a lot (parcel). Basically any kind of closed polygon defined as boundary will do.
Volumes dashboard gives us a tool to calculate multiple volumes for a corridor surface, or a surface that lies below multiple parcels. It also calculates volume for the entire object. For example, if you have a corridor design that is broken into phases, you can calculate the volume’s cut/fill for each phase and also put it all together or combine to see what your Phase 1, Phase 4 and Phase 5 have while leaving out Phase 2 and Phase 3.
Another scenario that is documented in help (there is a video too) talks about having 4 parcels and driveway on top of the surface.
Not only that but it gives you an opportunity to adjust cut and fill volumes and factors for specific areas as you change it-in real time! From there you can create a report or paste the calculation in your drawing. Volume Dashboard command is found in Analysis ribbon. Create Volume Surface in Dashboard by comparing two surfaces (EG and my Top corridor surface).
More about it after the jump.
For the sake of demonstration I drew a simple corridor, corridor surface, existing ground surface (EG) and two polygons which I will later use as boundaries. Here are some simple steps I put together.
1. Create Volume Surface in Dashboard by comparing two surfaces (EG and my Top corridor surface). This will create an entry you are familiar with.
2. Perform Surface Analysis (Analysis tab in Surface Properties accessible from the Dashboard). You may right-click on Volume surface and access Surface Properties directly from this dashboard. Also to be able to see the changes real time, I set surfaces to update automatically in my Prospector tab.
3. Once you ran your analysis you are ready to move forward.
4. Define Boundaries by closed polylines (on the parcel, around corridor area, feature lines, 2D and 3D polylines, etc.). The pieces will appear in Dashboard and will dynamically update any time there is a change. If necessary, use DRAWORDER command to move it back. You should be able to see the area, cut/fill, factors, etc. Cut will be red and fill will be green as set in Analysis' legend style.
This is where the real stuff begins. Now notice a new icon which will allow us to create another entry underneath our Volume surface. This will break it into smaller entries. Select one of the polygons and you will see it created with cut/fill. Familiarize yourself with other icons, too. If necessary, repeat this action for all desired regions.
5. From there you may want to create a report that will display in your browser or if you prefer- paste the summary of your results in the drawing.
Cool stuff, huh? Please come for more.
