Calculate the Volume of an Object

Dennis, Thanks for the plug in, very quick work. I have just run a few tests on some core shapes and answers are below. all based on 1x1x1 sized objects. I found that the default 12 pointed circle in AC3D when you create a round object caused a discrepancy in the result but as I subdivided the object the result moved closer and closer to the expected value (as you would expect but interesting to see)

__________Math_______Plug-in (default Circle)__Plug-in (after subdivide x3)
Cube______1.0________1.0
Pyramid____0.3333_____0.3333
Cylinder____0.7857_____0.75
Cone______0.2619_____0.25
Sphere_____0.5236_____0.48447_____________0.52137

Once again thanks for the plug-in excellent work.

Regards

Dave
