calculating volumes between two contours?

[SwChilly]

I have a pond surface. I need to calculate the area of the water surface (at a specific elevation) and calculate the volume.

 

Is there a way to do this?

Create a User Contour in your pond surface.

Extract the User Contour.

Paste Pond Surface into a new Surface.

Add the extracted User Contour as an outer Boundary in the new Surface.

 

Create Volume Surface.

 

 

The extracted Contour will be a polyline. You can get the area from the properties menu.

Brilliant! I forgot you can extract contours! Thanks so much!

Now that I have the surface made... what would my base and comparison surfaces be????

[SwChilly]

Never mind.. What I did was create two surfaces... one with the pasted surface of my pond, and then another one with the extracted contour added (so basically it's flat). Then I compared the two in my volume surface... Seems like a whole lot of surfaces just to get one result tho.. meh as long as it works

If you have the pond as a surface empty hole pretty sure just trying to remember steps you can do volumes by slices it gives a listing equivalent to going up in contour steps.
