Today’s good question comes from Ellie. She asked how to disable the selection preview effects. When selection preview is enabled objects are automatically highlighted (thickened and/or dashed) as you pass the cursor over them. This functionality can be helpful in many cases. But sometimes it can get overwhelming… especially in drawings that contain a lot of hatching, text, tables, xrefs, or groups. When you pass the cursor over a hatch, for example, you can get a flickering effect as the cursor moves across the many lines and spaces.
Fortunately, AutoCAD provides you with a significant amount of control over the selection preview behavior. In the Options dialog box, choose the Selection tab. You can enable selection preview when a command is active and/or when no command is active. Or you can disable it completely by turning off both options. When using selection preview, you can further control its behavior by accessing the Visual Effects Settings. In the Visual Effects Settings dialog box you can specify how the highlighted objects should appear, thickened and/or dashed lines, and you can access the Advanced Options to control the behavior for specific object types. If you like the concept of selection preview but are bothered by the flicker effect, try excluding all of these object types.
Thanks to Ellie for the good question!
