mark,
you might want to consider leaving all of your details in dwg / dxf platform as a standard, and use the solutions out there organizing them.
personally, I have used Columbus
www.oasys-software.com/product/dm/columbus/ . It works well for previewing, catalog-ing, searching out.... but you don't have the need to open another 'heavy' application like ACAD or Archicad. And Archicad imports (once you get the concept) 2d files so nicely, it might not be necessary to ever have these files in anything but dxf/dwg files, anyway.
Once I got my head around the concept that DXF/DWGs are a good tool to use WITH Archicad versus INSTEAD of, I found they could actually work together. DXF/DWG's are just lousy when it comes to parametrics.
