What software did you use?
Sketch Up. Invented right here in Boulder, CO and bought out by Google.
This would come in handy for a course that I am trying to write. Can I get a copy?
I’ll do you one better. Call me on my cell 720 272 8578. You fax me all the graphics you want for your course and I’ll have our two graphics artists make them for you. We’ll put them up in a special section of www.nachi.org/gallery/ You tell me what you want fixed/changed. We’ll edit them and put them back up. It will be fun.
