Hi all,
I had an odd corollary to the disappearing border and title block. I was trying to export a sheet layer to a pdf file for printing at an off site printer. The border was present on the sheet layer as I hit export then disappeared in the both the vectorworks drawing and the pdf file as the file transferred. The border just moved off the drawing and I can zoom out, find it and put it back. The drawing is set at the universe 0 origin. I was eventually able to make it work by exporting to a new file instead of overwriting an older version. Obviously I found a workaround, but I don't understand why it moved in the first place.
