Cut&Fill Volume: <Solid Error>

[higgins]

Hi all!

Okay, I have a very small and simplistic site model and I need to model a pond there, so, I thought to try my hand on the pad and fence tools... I can get the contours to change pretty much as I like, but for cut & fill volumes I get a confusing message.

Okay, my lowest pad is below the lowest contour line that I have, so the contours aren't perfect, but I get the same error when I simply build a small elevation on the model, so, this can't be the issue. What am I doing wrong?

Cut&Fill makes comparisons between the contours via sections.

If the site sections are un-closed polygons then a 'solids' error will result.

The Site Model must be closed before the Cut&Fill Procedure will work.

There must be a hole in your datum...

Thanks for the reply, but to test it, I drew a bunch rectangles inside one another, made them 3d polys and elevated them to a small rectangular hill... When I modify that, I get Cut Volume 0.0000 Cu M. Still no good.
