Cheers Dan, making tetra solids and just dividing the number of points
by 4 gives me what I need since I'm just looking for relative volume
changes.

Hi Si

If you're going down the isooffset route, make a tetramesh and count the
points - make sure the subdivions are evenly spaced and then multiple
the number of points by the cube of size of the subdivisions (e.g.
0.1*0.1*0.1 = 0.001). Hope that makes sense... There's a slightly more
long winded approach if you don't make the subdivisions even.

Cheers

Dan

Does anyone know of a way to find the volume of an object? I can create
an SDF volume using the isooffest sop but I can't see any way to query
the actual volume contained by it....

Si
