You can use the PARTIALOAD command to load additional geometry into a
partially open drawing.
NOTE When a drawing is partially open, named objects are still loaded into the
file along with the specified geometry from the selected layers. All layers are still
available in the partially open drawing, but only geometry from the layers specified
to load appears in the drawing.
Index Status
Displays whether the selected drawing file contains a spatial or layer index.
INDEXCTL controls whether layer and spatial indexes are saved with the
drawing file.
Unload All Xrefs on Open
Unloads all external references when opening the drawing. Selecting this
option enhances the opening process. If you partially open a drawing that
contains a bound xref, only the portion of the xref that is loaded (defined by
the selected view) is bound to the partially open drawing.
Open
Opens the drawing file, loading only combined geometry from the selected
view and layers.
