This is the big one Clyde Davies and I have been working on for almost 2 years...
CadFace is a plug in that works within Sketchup to give you super quick, super simple CADCAM files from the free or full versions of Sketchup
With CadFace you can design clocks, signs, pencil holders, puzzles etc.. there will be free design projects for schools on the CadFace site very very soon, and with one click of a menu within Sketchup, save a CAD file of that flat face which works in ANY CAD PROGRAM on the planet!
We have set up a UK distributor for individual and site licenses, and are open to offers from other territories... Contact us at ajbooker@yahoo.com
We expect to release a limited functionality free demo in 2 weeks time, and the full version will be available during October 2009, along with worksheets, teachers guides and other info
Send us some feedback and watch out for that free demo!
