From AVLAN Design:
AVD Mass and Volume Calculator is just the thing for measuring mathematics and physical parameters of composite objects in 3-D. It calculates weight, volume and mass for the figures of various shapes: prism, cylinder, cone, pyramid, sphere, water tank. The process of calculation is quite simple: after you select the object's shape, just define the sizes with the number of parts and press "Calculate" button to get the result.The ability to process three dimensional composite objects, even those which have apertures, expands the sphere of the program's usage as you will be able to work out mathematical and physical parameters of objects of most diverse shapes. The program includes such structural units as: plate, pipe, bar, beam, channel, angle and others.
