Hi All, I am mechanical engineer and software engineer ... but mostly worked as software engineer last ten years ... so now I decided to start some mechanical hobby project "to stay in touch with metal" just for fun and engineer passion I want to meet some interesting "mechanical people" on this forum and learn about differences between US and European standard, measurement units and so on ... because I am originally form Europe and thinking by default in metric system as well ... even after 4 years of my life in USA Also I wont to pickup some information how and where to order some small prototype parts for my hobby project. Locally in Las Vegas where I am currently located or in US or rest of the world. So what is best way to provide hobby blueprints in AutoCAD and get parts? Regards atko
