Where can i find the setting or button to use an entity on my model as the view center for rotation?  Currently when i rotate my model using the spaceball it rotates out of view.  Our parts are built in car postion and not about the origin.  Not sure what happened but i had a button that would allow me to set the center of the view.  I cant seem to find the correct search term to find the answer either.  When i do find it, im going to write it down.
