I am a newcomer to VW (2009 on a Mac) and have run into a strange problem that I would welcome some help with: My document file size has burgeoned to 1.75 GIGABYTES! It would seem that VW is storing all the history of all the changes made to each object within the file, even when the object is returned to a much simpler form. By way of a test I stripped my design backed to a single, relatively simple, 3D object: 4" x 4" x 165" with 6 areas subtracted from it and plain class texture applied. My file size reduced to 123 Mb. When I created the EXACT same object in a completely new document, the file size was only 220 Kb.
What am I doing wrong? Is there a way of purging all this unwanted 'history' that seems to be stored within the file? (using the 'purge unused objects' doesn't help).
Regards, Steve.
