There's a chart somewhere with the comparisons of features -- what's included, what's not -- all along the upgrade levels.
If you have a Jeep parked there in front of you, take a good straight-on photo (s) and include an easily identifiable and measurable thing in the pic. (when I do a wall install, a brick is that thing)
When you import the photo as a .jpg, just insert a rectangle that is the exact size of that thing. When they match in size after zooming/expanding, now you'll have a full-sized image on screen, allowing you to create the workspace(s) required.
