I received your software for deck planning and have truly enjoyed it. I was pleased with the simplicity of the program for design, working drawings and all the way through the list of materials. Everything that I design will be exclusively Simpson products. Thank you for being able to save me time on an ever growing demand for designing homes with decks and multiple levels.Gene D.
