You have twoi choices: Disabled and Enabled with Copy. From a user standpoint,
both allow people to work on Xrefs that are referenced in another drawing.
My preference has always been Disabled.
Using "Enabled" creates spatial and layer indexes in that xref, which simply
loads only that portion of the Xref which is visible in the original file. If
you have a huge plan in your drawing as an Xref, and you freeze out extraneous
xref layers, AutoCAD will only bring in that data which isn't frozen. Same thing
with Xclips. Yippee.
However, a layer thaw * in that drawing will then load all of that data back
into the file. Same thing with modifying an Xclip clipping boundary.
However, creating a local copy which Acad uses instead of a network version
doesn't do anything for you except create goop in your user's TEMP folder.
Autodesk's line is that you gain performance increases with Demand Loading
enabled w/copy; however, I've not seen this to be the case. I've not enbabled it
in A2K, but in R14 it performed rather poorly on our systems. Hence I've simply
disabled it.
