This looks like ten bucks well spent

[cham-ed]

I do jobs for customers that do not live near me. SU models makes sure I am building what they want BEFORE I make any sawdust. It is often after a couple of design iterations. Sure couldn't do that in my head or drawing by hand. I will admit I used expensive professional CAD software for years before I retired. I did find SU is a easier to learn than most of them. SU takes care of me for zero bucks.
