We are using PS with plain AutoCAD drawing. In order to do a "Where Used" search thru the drawing BOM's we have come up with a plan that involves creating an invisible block on each drawing with an attribute that contains a string of part numbers as follows: part1,part2,part3, etc. The file property has the full string and the item property has the full string. We are able to search and find any drawings containing the first few parts in the string but it appear there is a 50 character limitation built into the search engine.

Please remove this limitation or provide a work around.

Thanks,
Brad
