acDemandLoadEnabled

Turns on demand loading and improves AutoCAD performance. Other users cannot edit the file while it is being referenced.

acDemandLoadEnabledWithCopy

Turns on demand loading but uses a copy of the referenced drawing. Other users can edit the original drawing.

The initial value for this property is acDemandLoadEnabled.
