Solid materials

[jgb]

Now that SU is more adept at handling solids, at least giving us a very good volume calculation, a companion to that would be solid materials.

Give the Solid Materials (SM's) a density as well as a texture.
So if I select a solid and select "Steel" from the materials list, it not only textures the entire surface, but computes the weight of the solid based on the Volume times the density converted to the Units in use.

The SM list should also allow for user defined materials with user defined densities.
I.e. the SU SM list has a very few types of rock densities, but I might want to define a density for gravel.
In aviation there are several types of aluminum; each having very specific densities, while almost every other discipline needs only 1 common density.

That way I can get rid of the Excel spreadsheet I must maintain which gets very tedious when I make part changes in shape or scale.

And this just in...
SU should also give me the aggregate volume and weight of all the solids in a group (assembly).
