Partial Open option is available only for drawings in AutoCAD 2004 or later
format.
To partially open a drawing
1 Click the Application button, and click Open ➤ Drawing.
2 In the Select File dialog box, select a drawing.
3 Click the arrow next to Open. Click Partial Open.
4 In the Partial Open dialog box, select a view; the default view is EXTENTS.
You can load only geometry from model space views that are saved in
the current drawing.
5 Select one or more layers.
If you do not select a layer or layers to load, no layer geometry is loaded
into the drawing but all drawing layers exist in the drawing. If no layer
geometry is specified to load into the drawing, no geometry is loaded
even if the geometry from a view is specified to load. If you draw objects
on a layer that is not loaded, you may be drawing on top of existing
geometry that is not loaded in the drawing.
NOTE Xref-dependent layers are displayed in the Layer Geometry to Load
list only if the selected drawing was last saved with the VISRETAIN system
variable set to 1. Any layers created in the xref since the xref was loaded into
the drawing are not displayed in the Layer Geometry to Load list.
6 If the drawing contains a spatial index, you can select the Use Spatial
Index option.
A spatial index is a list that organizes objects based on their location in
space. A spatial index is used to locate the portion of the drawing that is
read; this minimizes the time required to open the drawing.
7 If the drawing contains xrefs but you don't want to load them, select
Unload All Xrefs on Open.
NOTE 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.
8 Click Open.
You can choose to load additional information into the current drawing
as long as the drawing is partially open.
