When I select a group of object or even if I place my mouse on an object it highlights that object. It kinda goes dashed. Anyways, is there any way to turn this off. I am running on a REALLY SLOW computer and just the act of it highlighting stuff bogs it down. I will XRef a floor plan into a drawing and lock that layer. Well when I work on top of it and I want to grab some stuff to stretch it, it grabs that floorplan and it takes forever for it to go through and highlight it. I appreciate any help. I tried looking through help on Autodesk but I don't know exactly what that feature is called so I didn't do well in finding it. Thanks!
