DRAWORDERCTL controls the display update and inheritance of draworder when using certain editing commands. The following commands are affected by DRAWORDERCTL: BREAK, EXPLODE, FILLET, HATCH, HATCHEDIT, JOIN, OFFSET, PEDIT, and TRIM.
With Draworder Inheritance on, entities created with these commands assume the draw order of the original objects.
With Draworder Inheritance off, they assume the default draworder (top).
With Display Update on, entities created with the aforementioned editing commands are displayed correctly according to their Draworder.
With Display Update off, they are displayed on top, until the next regeneration.
