I'm from the very old school and have a tough time learning new "tricks." All my work in AutoCAD has been simple plan and elevation views; pipe, valves, pumps, chemical storage tanks. An add-on for AutoCAD draws all the pipe, fittings, valves, a great add-on!
All are ANSI and the program will generate a BOM for me if needed.
I believe John wanted a 10 x 14 base, a 6" x 6" top, elevation of 6".
Perhaps you could post John's configuration if you are so inclined.
If we had the technology 40+ years ago, life in the sheetmetal business certainly would have been easier.
