To shorten the time for big x-ref (GIS or x-ref calling in 3D drawing) display, you could activate the “Demand load x-ref ” , and select “Enabled” or “Enabled with copy” as it’s shown as below.
This option needs to operate with layer “index” and space index, that is to say only when the x-ref file has clipping(space index, configure INDEXCTL as “2” or “3”), or when loading the x-ref which has freeze or closed layers(layers index, configure INDEXCTL as 1 or 3 ), the accelerated effect would be enabled.
