The VolumeOverlapped command calculates the approximate volume of overlapping objects without boolean operations. This can be useful for calculating the volume of objects that are difficult to boolean.
The WeightSolid command calculates the weight of a solid object by multiplying its volume by its density.
The WeightDensity command can be used to modify, add, or remove material-specific densities used in the WeightSolid and WeightOverlapped commands.
The WeightOverlapped command calculates the weight of an object by using the volume calculated by the VolumeOverlapped command.
