Sounds like we had the same "drafting classes"!! I don't have CAD software either. In this case I took the detailed measurements of the interior and rear of the FJ then drafted the 3 views by "hand"....then I scanned it in JPEG format...then opened the JPEG in Microsoft "paste", which allows some additional line work, coloring and text call outs....wala! It's a slow process, however,it works for me.Which program did you use for the diagrams? I took drafting class many moons ago in college and it was before CAD software was widely used, so everything was drawn/written by hand. I really like the layout.
How much will the platform weigh?
