I use Silo regulalry for my production work, in the toy industry.
I build models for prototypes to show clients.
But as you would think, it is a bit tough to use for some solids type shapes,
like trains and cars where something like MOI3d would be better to use.

I have just recently added MOI3d into my production work, after a year of
practicing with the bets versions.

I think I'm now better off with both in my toolbox.

They don't work in exchange of one another. meaning if I start
a model in one, I cant import/export for any real use in the other
software.
