Hi Pilou,

re:
> There is no Calcul Mass * Volume ?

Not currently but that's something that I would like to add in the future when I have a chance to design the UI for it. But if there are quite a lot of things to consider for it like should there be a list of materials that you pick from, do you need to enter in your own material types, is it necessary to have different densities assigned to different objects and have the mass of all of them computed together?

If all you need is a simple Mass = Density * volume calculation that is something done very easily with a calculator once you have the volume.
