I don't quite understand the problem or question.
As far as I know REVIT kind of ignores autocad Paperspace elements (title block, view ports etc) and only shows the model space elements which is where the lines, dimensions and text etc exist. Maybe make sure the CAD file is last saved in model space instead of paperspace to start with ?
You should not be opening the central file you should always make a local copy of the central file and once again as far as I know it just shows the linked autocad model spece elements.
Maybe the question needs to be re phrased ?
The process should be.
Save the CAD file in model space with zoom extents and 0,0,0 can't be too far away
Start REVIT, open a local copy of the central file.
Link in the CAD file and position accordingly.
Put the CAD file on it's own workset.
Pin the CAD file so it cannot be moved accidentally.
Save the REVIT file, sync and relinquish and close it the file.
Start REVIT, create a new local copy of the central file and everything should be there with no additional re-loading required.
