If you’re using AutoCAD 2009, you’ve probably noticed the tooltips that appear when you pass the cursor over an object. These are called rollover tooltips and they’re completely customizable!
You can control their display (on or off) with an option on the Display tab of the Options dialog box.
You can further customize the rollover tooltips by specifying which information you want to display, based on object type. This is the same process you would use to customize the Quick Properties.
In the CUI dialog box, you’ll notice a Rollover Tooltips node right below the Quick Properties node. If you select Rollover Tooltips, the right side of the CUI dialog box will display two panels. The first panel displays a list of common object types for which you might want to customize the rollover tooltips. The second panel displays the general properties that are available for all object types. You can add or remove general properties to quickly change the default tooltip properties that are displayed for every object, regardless of object type.
If you want to customize the rollover tooltips for specific object types, you can select the object in the first panel. If the object is not listed there, select the Edit Object Type List button at the top of the Panel.
Selecting that button displays a list of all available object types. The objects you select in this list determines which ones are displayed in the first panel of the CUI dialog box and, therefore, available for you to customize.
When you select one of these object types in the first panel of the CUI dialog box, all the available properties for that particular object type are displayed in the second panel. You can then select which properties you want to display in the rollover tooltip.
