Thanks for asking! I'm with GrabCAD's Community Support team, and I wanted to make sure that you heard from us on this. FredSWUG was correct - all of our badge's requirements are listed here (https://grabcad.com/badges). What we are not as clear about is how these badges are awarded. Some are automatic, once you have achieved a certain specific goal. Others are awarded manually by us.
Which badge in particular are you asking about?
