Well, the IFC issue has gotten 'sortav' sorted out.
here's what I had to do.
1. create a blank AC14 template file.
2. open 2 sessions of AC.
3. recreate the story settings that are associated to the IFC file (since this one didn't seem to want to play well with the other file).
4. Once all stories (both story number as well as heights) are setup right, then I began to cut/paste story by story from the "NEW" building file, into the "EXISTING" building file.
5. since I knew the "NEW" building file story settings and wall placements were done right, it was relatively straight forward to copy the components story by story.
6. Once the EXST file was then hotlinked into the NEW TW file, it behaved correctly.
So: moral of the story.
Make sure your "story numbers (uneditable numbers)" as well as the "height to height" and story height placement starting points ALL match up from one TW file to the other.
