How do I calculate the Volume of an Object?

There is currently no access to the Measure Utility from MAXScript, but you can use the following MAXScript function to get the same results:

SCRIPT

   fn CalculateVolumeAndCenterOfMass obj =
   (
       local Volume= 0.0
       local Center= [0.0, 0.0, 0.0]
       local theMesh = snapshotasmesh obj
       local numFaces = theMesh.numfaces
       for i = 1 to numFaces do
       (
           local Face= getFace theMesh i
           local vert2 = getVert theMesh Face.z
           local vert1 = getVert theMesh Face.y
           local vert0 = getVert theMesh Face.x
           local dV = Dot (Cross (vert1 - vert0) (vert2 - vert0)) vert0
           Volume+= dV
           Center+= (vert0 + vert1 + vert2) * dV
       )
       delete theMesh
       Volume /= 6
       Center /= 24
       Center /= Volume
       #(Volume,Center)
   )

   --Call the function on a geometry object - the result will be a list
   --containing the Volume and the Center of mass in local space.
   s = sphere()
   theVolAndCom = CalculateVolumeAndCenterOfMass $Sphere001
   --To get the world space of the Center of Mass just like in the Utility,
   --you have to do some extra work:
   theComInWorld = theVolAndCom[2] * $Sphere001.objectTransform
