OPTIONS
Open Part of a Large Drawing (Partial Load)
If you work with large drawings, you can use the Partial Open option to select
which view and layer geometry (graphical objects only) that you want to work
with in a drawing. For example, if you load geometry from the
EXTENTS view
and the
SITE layer, AutoCAD loads into the drawing everything on the SITE
layer that falls within the Extents view.
You can only edit what is loaded into the drawing file, but all the drawing’s
named objects are available in the partially open drawing. Named objects
include layers, views, blocks, dimension styles, text styles, viewport
configurations, layouts, UCSs, and linetypes.
By organizing large drawings into sectored views, you can load and edit only
what you need. For example, if you work with a city plan and need to edit
only the southeast sector (sector D3 in the illustration), you can load this
drawing area by specifying the predefined view. If you only need to edit the
city plot numbers, you can load just the geometry on this specific layer.
