I have a bunch of "bloated" drawing files with multiple layouts in each that take a long time to open and regenerate due to large xrefs attached that were created with Civil 3D. I want to break down the multi-layout files into single-layout files and eliminate all but one of the layouts in each file. To save time, once the file is open, I unload all the xrefs and then delete each layout (one-by-one). However, I'd still like to eliminate the initial time it takes for the files to open before I can unload the xrefs.
Is there a command switch that will enable me to prevent the xrefs from loading when I call each file to open; and can it be set up in a script somehow? I've been using AutoCad for about 12 years now and this is the first time I've had occasion to need to do this. I'm still very inexperienced with Civil 3D (2006), but I realize the load this stuff imposes on file processing is tremendous (unless I just don't know the tricks to get around my old-fashioned working methods).
Any help will be appreciated.
