Erase Objects
There are many ways to delete objects from your drawing and clean up the
display.
Remove Unused Definitions, Styles, and Objects
You can remove unused named and unnamed objects with PURGE. Some of the
unnamed objects you can purge include block definitions, dimension styles,
layers, linetypes, and text styles. With PURGE you can also remove zero-length
geometry and empty text objects.
Clean Up the Display
You can remove the plus-shaped markers called blips and stray pixels that
may be left over from some editing operations from the display area.
■ To remove blips, use REDRAW.
■ To remove stray pixels, use REGEN.
