The Development of the Truss Plate, Part VII: Contentious Competition Joe Kannapell The plated truss industry went bonkers around 1961.

Design Connections: Building Information Modeling for the Component Business? Geordie Secord If I compare the truss layout and design software used in the early 1980s to what is available today, it’s mind boggling. Actually, comparing layout software wouldn’t be possible since the first layout software at our company didn’t show up until around 1989! Up to that point,...
