Once a symbol instance is placed in a drawing, its information can be displayed in the Object Info palette. Select a symbol instance to display its properties. A symbol’s location can be adjusted, or its layer and class association can be changed by selecting a new class or layer from the appropriate list. A symbol can be replaced with another symbol, rotated in 2D or 3D space, and, for symbols located in walls, flipped, replaced, and repositioned.
Most of a black symbol’s physical attributes cannot be directly changed in the Object Info or Attributes palette. Instead, the components of a symbol must be accessed and edited through the Edit Symbol window. Changes made to a symbol definition affect all existing and future instances of that symbol, unless the symbol was inserted as a group (blue) or plug-in object (red).
If you delete a symbol definition and there are instances of that symbol in the drawing, you can specify whether to replace all instances with loci or to delete them completely.
