No, you probably don't. If you can draw a line and a circle using MS Paint you can learn Solidworks from books*, online and by just doing. I took one college class in SW after using the program for about 3 months on my own with the hope/intent of steepening the learning curve. It didn't. BUT..... It did show me just how much potential there is in the program that I had no idea existed. That was worth the time and money. From there all you need to do is have a goal or desire to draw something and if you can't figure it out - there is a YouTube to show you how. I'll also note here that the same thing has happened to SW YouTube videos that has happened to YouTube in general - Finding good video is getting harder and harder due to the increasing volume of junk postings. * Books. Old school but still one of the best sources of information in existence. Even old texts, like for SW versions a decade or more older, have the same basic information. Much like physics and math the basics haven't changed much over the years.
