These kinds of exact and technical files hurt my head a whole lot more than the 3D ones. With the price of the windows I suspect it is mostly the pressure of getting everything perfect the first time. For the cutting of the window bucks which would be made from plywood I first simplified the drawings keeping only the outside border. The bottom of the window bucks needed to be cut away so we could pour concrete into the forms. To maximize material usage I fit the smaller windows inside the bigger ones. I also put some runs holes in the largest pieces to make them easier to handle.
The next task was to make everything fit onto sheets of plywood/ The tallest pieces were cut to size by laying over a rectangular vector and using the jigsaw tool. I nested everything by hand. Each file will be cut twice (except the last one which was already duplicated) meaning the window bucks will require twenty five sheets plywood.
It shouldn't take long to whittle the parts, much longer to fit them together. I'll post some pictures of the pieces as they go together. Stay tuned...
