Have you considered a 3D package on the PC... Not sure how long it took on paper, however, I did this in Sketchup in a few minutes, and it took most of the time colouring it in.
Not necessarily spruiking Sketchup as there are many 3D designers available.
Even using layout lines for 2D, which only took me about 20 minutes just to do those 9 rhumbi... hell, I now appreciate your effort on paper... my head is spinning after that.
Cheap and woodwortking in the same sentenc is an oxymoron!
I have what is known as Hyperphantasia. I have the ability to "see" it in my brain. Setting it down on paper or melamine as it were is actually quite simple. Once scale has been established, this took less than 5 minutes. Having worked years in a ship/boat building CAD enviroment I found for one offs or repair projects our time was better spent on hand done plan and elevation drawings than re-inventing the wheel inputting data to CAD to produce the same thing. The physical job usually took less time to perform. Here again I don't re-invent the wheel for each project. Most are done to the same 30 degree angle (R & L) from the perpendicular. No guess work and each representation is made from the same size material. Keeps everything simple. All that said, the miters still have to be accurate so I'm still on the hook for the craftsmanship part as well.
