You can display and change the current properties for any object in your drawing.
The Properties Inspector palette lists the current settings for properties of the selected object or set of objects. You can modify any property that can be changed by specifying a new value.
You can double-click most objects to open the Properties Inspector palette when the DBLCLKEDIT and PICKFIRST system variables are turned on (the default).
Several types of objects open an editor or start an object-specific command when you double-click them instead of the Properties Inspector palette. These types of objects include blocks, polylines, splines, text, and more.
