DEFPLSTYLE (System Variable)

Specifies the default plot style for new objects in a drawing when opening a drawing that was created in a release prior to AutoCAD 2000, or when creating a new drawing from scratch without using a drawing template.

Type: String
Saved in: Registry
Initial value: ByLayer

When the drawing is opened and PSTYLEPOLICY is set to 1 (color-dependent plot style mode), DEFPLSTYLE is read-only and has a value of "BYCOLOR." If PSTYLEPOLICY is set to 0 (named plot style mode), DEFPLSTYLE is writable and has a default value of "BYLAYER."

To convert the current drawing to use named or color-dependent plot styles, use CONVERTPSTYLES.
