Hi Jennifer,

I haven't been a big user of it yet, but warming up to it :), and have verified
that it works for the sphere.py example (an isosurf for a unit sphere),
producing the very close answer of   sphereVol= 4.18355538824  (cf.
4*pi*r^3/3).

I'm assuming you have a non-trivial closed isosurf and are able to "correctly"
calculate its volume by some other means?
