ok here is how i sorta worked around the problem
i dont know if this first step helped, but i did it
before i did the last step
go to applications>utilities>terminal>
type
# defaults write com.apple.finder AppleShowAllFiles -bool true
# KillAll Finder
press enter.
then go to applications>vectorworks and right click the application
logo, and click on "show package contents"
then
contents>MacOS-DWG>MacOS.dwg
if you open up that last file that is the one you are looking for.
you can take it out of there and rename it and it is as good as
any other file.
the only thing is that everytime you export the new file goes right
into that folder.
