Ive tried google sketch, it was very confusing. maybe ill try it again if no one has any other suggestions. I looked into "Cad Pro" the website seemed exactly what i wanted, but user reviews are horrible.
If Sketchup is confusing you need to learn it before you move on to other programs.
I'm finishing 5 years of architecture school and they didn't teach us a single program. You have to sit down and force yourself through one program regardless of what it is. If you can't do that with sketchup then your out of luck.
