I having difficulties running the fVolume.vlx on ACAD2014. Is there any update for this routine? thanks in advance. =)

What difficulties are you experiencing specifically?

when i run Fvolume and select the 3d solid it does not show the value... it only display #### m3

I thought you would never reply so I downloaded and tested the program myself.  I can confirm the same results using AutoCAD 2014.  Have not found a fix for it yet.  Will keep trying.
