Procedure

There are several features that can improve performance when dealing with large referenced drawings.

Overview of Demand Loading
Provides a high-level description of using demand loading to improve performance when working with large referenced drawings.
Unload Xrefs
When a DWG reference (xref) is unloaded from the current drawing, the drawing opens much faster and uses less memory.
Work with Demand Loading
With demand loading, only the data from the referenced drawing that is necessary to regenerate the current drawing is loaded into memory.
Work with Layer and Spatial Indexes
To receive the maximum benefit of demand loading, it is recommended that you save any drawings that are used as xrefs with layer and spatial indexes.
Set Paths for Temporary Xref File Copies
When you turn on demand loading with copy, you can control where copies of externally referenced drawings are to be placed.
