IPTW 2017 - The Preservation Trades Network - will be in Detroit at the Detroit Yacht Club Sept, 8-10.
I will be teaching 2 sessions on how to draw squares with a compass, how to layout frames using geometry as we did 200 yrs ago.
And some history (Vitruvius, Palladio, Serlio, Gibbs, even Isaiah in the Bible! ) on the side.
Of course the use of Practical Geometry didn't stop 200 years ago. The knowledge came with the settlers to the Mid-west. Houses and barns, public structures were laid out and framed using the honored patterns.
I will include examples of mid - 19th century framing and design as well as earlier 18th c. antecedents.
You can come. http://ptn.org/iptn-2017
