I am taking baby steps with Solidworks to make parts, but am getting the hang of it with the help of a fantastic web site http://cadjunkie.com/ . A young man named Adam is producing some really good training videos. They are the best I have found and a lot of fun. Adam is informative and funny and has a good sense of tempo that makes his videos a valuable learning tool. Here are some pictures of my latest attemps at the drive wheels for the Locomotive model.
