We are also having various other trouble with our file, which was the first one to use a set of template symbols I created. Here's how Lesley describes the problem:
1. Whilst working on a new architectural drawing with 2no. Layers, existing and proposed, I have been creating classes for various levels of information for use on different sheet layers. The class I have most recently been working in has vanished and all information in that class has been reassigned to another class. This happens between the drawing being saved and closed, then reopened again. When I try to recreate the vanished class vwx tells me the name is already in use by another object. There is no class in the list with the name, so I cannot see how this has happened. Purging the document of unused classes does not appear to help.
2. Working on the same project, we have been using ?sheet border? items for floor finish, wall finish, ceiling finish markers etc. A similar problem has been happening with these, in that the symbol within the sheet border item has vanished and no longer appears in the symbol resource browser. Although the sheet border/symbol still appears in the annotations, when I double click on it or try to duplicate it, it disappears. When I try and paste it back into the drawing from another file the dialogue box tells me the name, record formats etc are in use (sometimes by a 'group'). Again, purging doesn?t help, I also tried to custom select the group with the name and nothing is selected.
