first time using the BOM tool in sw2004sp3... In column properties, trying to link contents to custom properties of the assembly model. When I select "user defined" I would have expected it to list any user defined properties within the assembly model file, but that would have been too easy, I suppose. Instead it lists only the some default document properties (I think these are properties for the drawing file). I can't see any of the model's user defined properties and typing in a value is locked out. Only list selection can be done at this point. I hope I am missing something simple, or else this tool is pretty much worthless. Any ideas? Thanks Bill
