Cool list ! Don't know 3DSPlash...
and for the collector : http://www.anim8or.com ;)

I am suprised to not see an interesting one : FormZ (Nurbs) Less ergonomic than Moi
but very similar to Sketchup + Nurbs (previous Bonzaï 3D (?)





who has a free Version: FormZ Free (Only Nurbs surfaces for this last one) - minutes 25




Export Sat from Bonzaï 3D, FormZ works fine with Moi! :)



with test some different materials inside Owlet - here the green one seems very cool!:)
