Today's good question comes from Ketan. He asked how he can hide the camera icons that are automatically displayed when he creates cameras/views in AutoCAD 2007 (and 2008).
When you create named views using the CAMERA or VIEW commands in AutoCAD 2007 and 2008, AutoCAD automatically places a camera icon to represent the viewpoint location of each named view. If you have a lot of named views, your drawing can seem cluttered with camera icons.
You can toggle off the camera icons using the CAMERADISPLAY system variable. It is also accessible from a button on the Navigation panel of the Dashboard.
