I actually own two licenses of Post Frame Manager. Prior to that I used Construction Maestro. The reason I started with the graphical drawing part first is because other software does not do nice 3d renderings.
For me neither Construction Maestro nor Post Frame Manager’s 3D renderings were acceptable. Also Building Creator allows me to design a building much faster while drawing it instantly as changes are made.

At this time my program is not claiming to be an estimating program but the pictures definitely sell buildings. I own a lumber yard as well as a construction company with four crews. I can tell you with certainty that my salesmen use Building Creator every day. They tell me they couldn’t do their job without Building Creator.
I hope to some day create a solution that does estimating & blue prints, but as you mentioned it’s a tremendous amount of work. I have done enough of the ground work to say that when I do complete a solution it will be state of the art. It also will be a separate program from Building Creator, and will have it’s own 3D graphics built-in, so it won’t rely on SketchUp at all. Of course it will also be worth significantly more than $1000 at that point.
