You can now access the presentations from SolidWorks World online. You can get recorded video of the sessions or a powerpoint, if available. This is a great way to attend for free and at least get the benefit of the presented materials. This is one of the nicer things SolidWorks does for users, so you should take advantage of it. Many presentations come from SolidWorks employees, and some from high level users.
When you download the powerpoints, they are given creative names like “3560.pptx”. For your own archive, just rename it with the name of the presenter and/or the topic so you’ll know what it is without opening it. Plus, don’t be afraid of the “pptx”. If you have an older version of powerpoint (I have 2003), it will convert with a little help from an automatically downloaded plug in. Just think. For years we called Microsoft “evil”, yet even their data is compatible with all versions of their software.
