Actually this looks like a fairly trivial thing to add, there's a single function in the hdk that seems to do the job.

Or since it needs to have an SDF to get the value calculated, a checkbox 
to the isooffset that creates a detail attribute called volume.

However I admit it's more logical for a user point a view to have it 
along the measure sop. Maybe an auxiliary input to pipe the SDF inside 
the Measure Sop.
