It is a small miracle that I am able to design in 3D on my 2008 Macbook. I use a program called Sketchup Pro, which will export images in a program language called .dwg – from which the computer controlled router at CNCRoutingAZ in Chandler will do its thing on a sheet of exterior-grade 3/4 inch plywood. It took me about 40 hours of intense work the past two weeks to get the designs for both the Entry Arch and the Full Arch with 37″ sidewalls ready for production. If I get milled components in time to do some finishing work I will be assembling the Entry Arch for show at the Envision Tucson Sustainable Festival on October 18th. After that I am installing the Full Arch over a hugelkultur bed belonging to Dale and Julie in a midtown home in Tucson. See images below.
