Ken, nice design, If you were to make this layout a 5×12 what is the best way to stretch it out. I am trying to figure out a area on our main layout, that is 6.5 by 17ft. Something like this would fit in the center nicely. Also how hard is it to make your plan 3D like you have done in the past. It helps in determining the grade for me.
Thanks for posting this, it has given me a few ideas. Nick T.
