I'm having issues previewing parts in EPDM/eDrawings 2012. The attached messages pop up when trying to open a file.

I went into the file to see if the 'Save tessellation with part document' field was checked, and it was.

Based on some research - simply opening the part and re-saving the document seems like a possible fix.

I am currently in the middle of transferring data into EPDM, will saving and converting old files to the new form affect assemblies and any other linking that was initially established?
