Hi David,

thanks for the help. I modified the example and managed to get a volume
for the sphere. However, it doesn't work when I use a polydata (that I
read in from a vtk file). I used GetBounds to determine the final volume
size, therefor I can't be missing the polydata.

Any suggestions ?

thanks,
Hari
