I still do all my drawing by hand, having been a plumber, plumbing contractor, general contractor 48 years, and designing all that I built. I think much better drawing by hand, 'installing' the complete electrical, plumbing and HVAC systems as I draw the architectural. I could not work the way that I work without your product. Some design jobs require your 36 x 24 title sheets with fade out grids. I need them to get the job done!
