I'm currently working on a project that essentially involves documenting 2D DWG's into a 3D model comprised of linked mechanical, structural, and architectural models. Of course this means frequent reloading of dwgs. The mechanical model gets by far the majority of my attention, and I'm generally reloading at least 1 new dwg file every day, the trouble is each time it takes an 1 to 1.5 hours to "reload from" the latest drawing. In an attempt to speed things up, I've moved everything off the network and onto my hard drive, unlink dwg files not in use, and purged the models to reduce size. The dwg files are all saved to a network, however before linking them into Revit, I detach all unused X-refs, and bind in any I am using, then audit, purge, and overkill before saving a copy to my hard drive. The mechanical Revit model is 130MB and the dwg links are around 15MB (rather large I know, but I'm not sure how to reduce them any further in size). The interesting thing is the structural model is even larger at 145MB, yet takes only a minute to open and relink dwgs.
I presume the long opening times and reload times are related, as when opening, the status bar on the bottom left displays the name of loaded dwg files.
Can anyone provide some insight into why these files are taking so long in model vs. another?
Thanks
