You could probably schedule it. I haven't done it myself but you could certainly extract areas of ceiling material. Using formulas, you should be able to calculate the grid quantities.
Hi Ted,
Are you using a Ceiling Grid tool to create the ceiling grids in question?
As Doug mentioned, you can add properties to ceiling grid objects and use Data Extraction to export the information based on the custom properties you've added.
Is this what you're looking for?
Yes. However I don't know if that will give me the level of detailed parts I need. There are main Tee's that run front to back on 4' centers with 4' Cross tee's that run between them, then 2' tees that create the 2x2 grid and an angle that runs around the perimeter of the space. I may have to try a LISP routine or something along that route.
A Ceiling Grid object is not going to give you that information as an automatic property. I am not sure what data might be derived via a formula property from the model. One concern would be if a Polyline or Space were being used as a clipping element, and whether any data retrieved from the Ceiling Grid object would reflect the overall size of the grid or the clipped size. It may be easier to apply estimating rules of thumb based on square footages.
