Solids and also layout drawings like with SW and IV and also does it allow you to work with solid modelling?
Wouldn't say an absolute no to this...
Yes you can make models "water tight" which can be considered a closed volume that you could consider a solid. There is also a "solids" menu which has some features that do just that.
What you won't find is a straight 1:1 environment like SW or IV when it comes to making drawings. You can make drawings in Rhino, but i wouldn't suggest walking in expecting it to look the part.
Thanx Arthur for your input
Rhino 4 and then particularly 5, fix the drawing drawback, especially if you have the "Penguin" plugin. I use it for all of my 2d illustration needs.
