Nope. The destination file is a clean, barebones new document (typical/default Vectorworks blank new document).
What I did discover was a door object had a value of zero (0) for the door width. It looks like a door object had been used for its sidelight only instead of just using a window PIO to do the job; deleting the door before copying to the new/blank document solved the problem.
I suspect there are a lot of PIOs (doors, windows, columns, etc.) that do not like having a zero value in critical height/width fields.
