Very cool. My "traditional" background is is pen and paper drafting. Many years ago I helped design the concrete forms that were used to make the monorail and epcot center at Walt Disney World. I also worked on formwork for hundreds of highway bridges, and various turbine pedestals for power generation across the U.S. and Canada. I pity the fool who has a job where they have to deal the the U.S. Army Corps of Engineers.
