Ed has posted his presentation from SolidWorks World 2011, as linked above. This is a great presentation for anyone who pushes SolidWorks' modeling to the limits. He discusses many finer points of advanced modeling, specifically for plastic part design.
- I wanted to mention this presentation specifically on the forums, but I probably won't be linking any new SolidWorks presentations from SWtuts.com. I will, of course, respond to people's questions with links if the presentation might be of help. If you are interested in following newly posted presentations on that site, I suggest you follow the RSS feed http://www.swtuts.com/?feed=rss .
