Hello, this is my first post to the forum. I am using ADT 2007 and have just made the jump to Project Navigator. It has definitely been a learning process--sometimes on a minute by minute basis--but I have already fallen in love with it. I am working on a rather large project (84,000 sq.ft.) and have been creating custom property sets and custom schedules for the project. My question involves my finish schedule. I currently have the finish schedule referencing a "spaces" construct for all of it's information and have used a ceiling height property set for the corresponding column in my schedule. My problem is that there are a number of rooms that I would like to have "EXP" (for "exposed") as the value in the ceiling height column. The property set is obviously looking for a dimension value here, so I can't type in any text. Conversely, this project has well over 100 rooms and changing the property set to a text value and manually entering each height is a tedious process I would rather not do if I can get around it. Lord knows I have enough text values in my property sets that already require this approach. Is there a workaround for this that I am missing? Thank you in advance for any help you may offer.
