New CAD Package: Upverter

We’ve added a new, free CAD package called Upverter. It’s a web-based application and it’s normally paid for on a monthly basis. But if you make all your designs open-source (not  a problem for most hobbyists), access is free and it appears there are no crippled features. It looks intriguing. Has anyone tried tried it? If so, please write a review!
