Pond Volume by Contour-Automatically?

[timdodds]

Does anybody know if it is possible to have AutoCAD calculate the volume of a pond at various elevations without having to manually generate a surface for each elevation?

Thanks in advance,
Tim

I can't think of a way at this time. Volumes in Civil 3D are surface based.
Surfaces need to happen if volumes are needed.

I ran a surface evaluation at 1 foot increments. Then generated a table which gives you the area (volume). Double check your areas though. I haven't perfected the technique

There is a great article by the infamous James Wedding, P.E.
here is a link
http://www.civil3d.com/index.php/2006/05/surface-area-table/

This is a function of Civil 3D.

Other than extracting the area that is bound by the contour and manually calculating the volume based on depth between contours, I don't believe there is any other way to do this in vanilla AutoCAD.

Why not just set the volume desired in the pond design wizard?..Oh yea thats right Civil3D doesnt have that feature that is the "other" powerful civil package 😉

I tried that and keep getting this message in that other software.

Maybe James will elaborate a bit on his article. I'm a bit confused by the
results in his table.

If you know vlisp you can create a routine that will build the table for you (OR VBA which I used). I'm in the process of re writting my routine for the guys in another department that do a lot of tables with volumes.

I gave James' method a go and I am confused by the results in MY table. I copied a 2D surface, gave it a contour interval I liked, exploded the copy and found that the results in my table were nothing like what the exploded contours gave me. For starters although I could go in an manually change the breaks in the intervals, I couldn't control how many intervals. I would say 10, and it would give 5. So would say 20, and it would give 7. But even with the intervals the program chose, the values were a magnitude of 10 times greater than what a third party software gave me.
Oh well, no time to trouble shoot. I'll wait for 2008.

There is a routine in Many Areas, stage storage volumes, that will calculate
the capacity of the pond froma model at user defined interval. Many Areas

My results were the same. Tanya West (support in Manchester) was successful
in achieving a desired number of ranges using user-defined contours.
Apparently, there is no default value for ranges for that analysis type so
what you spec is what you get.

If that method works on the range issue, there is still the problem of the
output. I expected what I consider to be a standard stage-storage table:
increasing volumes per user-specified increment. That's not what I got.

This thread is already a couple of weeks old. I'll re-post it to see if we
can stir up something.

Sorry, just saw this. It was actually a Dana post. If you'll post specific
questions, I'm sure she'll reply.

that post needs to be pulled. it was originally civil 3d rocks post that got migrated. i pulled it from rocks, but apparently not civil3d.com

here is the method that i currently use:

and the table for it i will post later.
