If you are interested in participating in SolidWorks usability testing, check out the post on the SolidWorks Blog for details. They are looking for folks from all skill levels to do exploratory, free-form usability test on development builds of SolidWorks.
Most of the time, the tests are done online, and you will get to see possible new functionality and have input on the direction of the software! Sign-up is free and all you have to do to sign up is fill out a short survey.
