AutoCAD Map 3D :: Insert DWF Into DWG File?

I have been trying to insert a dwf file into a dwg file, so that I can do some work on the map, so that I can then print out the new data, overlaid on the older, dwf data.

I am aware that I'd not be changing the contents of the dwf file.

My problem: AutoCAD Map keeps crashing when I zoom out to include the dwf file in my field of view, or when I zoom in to begin my work.

This is not one or 2, or even 5 crashes. I'm up to 15+ crashes now.

I've stripped all unnecessary components, turned on, unlocked, thawed all layers, removed all unneeded items. I've run purge, audit, recover, saved for each event, so as to not lose the data once the crash occurs.

My last attempt was to take a brand new map, with no data at all, and then attach the dwf file. Once I'd done that, saved the attach operation, I went to zoom to extents so I could begin the work, and-- you guessed it-- Map3D crashed!

I've filled out more error reports than my colleague who uses ArcGIS by ESRI, and they're constantly crashing.

While the dwf file was originally located on another server, due to a sufficient number of crashes yesterday afternoon, I decided to copy the file to the same file location as the dwg map so to reduce the possibility of restrictions on the server that AutoCAD would not cope with.

I simply want to do some overlay work-- which at this point will consist of just copy/pasting data-- to the dwf map file.
