Grappling with CAD

I've always enjoyed doing pen and ink framing drawings but they are time consuming and limiting compared to the capabilities of modern CAD programs. Finally I've taken the time to get to grips with a simple but effective package, and am already finding how much easier it makes so many aspects of the pre-workshop stages. Customers get a clearer impression of what they're getting, builders and architects can visualise and discuss techincal details, and I save hours of time producing my drawings. Not such a luddite after all!
