By the time I was done with the first tutorial, I had learned to design a simple 1 room cabin in 3D and the total time was less than 10-15 min, and when done I could turn it around and look behind it, and see walls on the opposite side of the house through the window and door - it was absolutely amazing.
Best of all - basic SketchUp is *** free ***.
I don’t normally do this kind of thing, but the controls were so easy to learn, that it’s to useful a tool to keep hidden.
Sorry 'bout that. I have gotten to the point that when someone says 'This CAD is easy to use" that I usualy ignore it - because it turns out that it isn’t easy until you go over the steep learning curve.
I went back and looked at the post you made, and SketchUp was burried with several other CAD programs, and it was probably missed because of that.
I downloaded it last night and started on the tutorials today… and here I thought I would never be able to get the hang of 3D stuff. No to do some buildings!
