Grading Calculation - volume of excavation from a mesh

[Scott Bulmer]

Greetings, I need to calculate the excavated volume of soil from a mesh as it relates to a swimming pool. The pool is on a sloping mesh as seen in the attached image. For a grading calculation, is there a way to accurately calculate the volume of where the mesh intersects the pool? For the purpose of this discussion the pool can be one large slab. Thanks for any suggestions. Scott

Create a schedule for the mesh and calculate "Net Volume", you will have to run the schedule with and with out the seo of the pool. The difference in the volume calc's is the excavated volume.

Just create a duplicate of the mesh without the SEO so you can calculate both at the same time and you don't affect the existing mesh SEO.

It is a bit of a pain the a 'Net Volume' works for a mesh, but there is no such thing as 'Gross Volume' for a mesh (or 'Conditional Volume' either).

It worked~! Thank you both for your suggestions, As recommended I used duplicate meshes with and without the SEO calculated in a mesh schedule. That is a very handy grading calc technique. Scott

Understood that issue is solved...
But there is yet another option
(if you are on an ARCHIPLUS subscription).
Download the "Terrian Tool".

Full discloser... I've never tried it.

Thanks Marc. Also, I just learned that the opening tool in AC23 when placed into meshes can yield the volume of the hole or excavation volume. Very useful. See the attached screenshot. Scott

Im not certain this is measuring the volume of the excavation, When I do this, it measures the volume of the opening tool, maybe there is another selection option in the schedule.

i am using Zones in 3d to draw the excavation area and then i use SEO (subtract by upwards extrusion) with the original terrain.
This is working for us so far because we can schedule the excavations easily also the zone comes with a stamp so a lot of info is displayed there.

One question though.
Can i measure the volume of a zone after a SEO?

(please say yes)

Thank you both for your suggestions !

here is my workflow, to automate the process
you have to duplicate the original terrain , change it's material and ID like shown
