Build a garage with a 10' Front wall and a 8' back wall Roof 12/12 pitch with 3' front overhang and usable attic space

If you can take a pic, you can measure it.  Use the measurements and do an asbuilt!

I figured out how to do it by building the roof with the back wall 18" back then moving the back wall forward the 18" on the first floor

Great job!  Now play with the pitch a little.  Select both planes, lock fascia height, see how it looks at 11, then 10, then 9.5, and keep checking how much ceiling you get for each up in that upper half-floor.

 

Then raise up both in the z direction.  Look at the photo again.  The front fascia height looks to be up around the ten foot elevation.  Rear maybe eight.
