Hi all, I'm new on this forum and also very new to mechanical engineering... in fact I only had technical drawing at school which I was really good at. I almost never forgot anything but I don't practice at all. I am now a Software Engineer and also am very good with electronics (or so I think) but I always manage to achieve what I need I am here to clarify some terminologies in mechanical engineering and also to understand better diagrams as you can imagine, school level is not high enough for any project. I am using SketchUp to draw whatever I need in my designs and will be asking some questions here and there Cheers C
