I am attempting to compute the number of joists components in a box whose boundary is defined by an object A x B. The property object only offers, under the "proportional with" field: Item, Length, Surface A, B, & C, Volume, and Custom. No matter what size the bounding box is the component quantity in my component report remains constant, only adjusting by modifying the quantity multiplier in the propery object.
How do I capture the B field from my object bounding box for use in property objects?
