I don't know when I first saw it (it may have been years ago now), but I've noticed that there is a little blue circle indicating the center of mass of my part that is always visible while I'm modeling. While this is a very useful feature when you need it, I don't need to see it ALL the time. Does anyone know of a way to turn this off? By the way, I'm using SW 2010.
I believe it more related to your 3d mouse or space navigator. Check these if you use space navigator
What is the stupid blue circle thing in SW2010 Windows 7 screen? OR mystery blue circle
