Percentage of wall openings

[angelo]

Hello,

I've tried material takeoffs and wall schedules with no luck so far. For buildings where there is a close adjacency, we need to calculate opening percentage for a wall. Both wall properties and material takeoffs for the wall only give me net. I need the gross square footage to get the percentage of openings.

Any suggestions on how to schedule or tag this? During the design process the percentage of openings will change, so I'd like to have something that can stay up to date.

Thanks,
Angelo

Quite an old post, but I'm currently trying to do this and was wondering if there is an "easy" way for Revit to calculate this? To add to the complexity, we only need to do this for one level...

You know, there are some new reporting parameters in Revit 2011. I wonder if they could be used for this...

Most examples I've found only show external families, not system families, so not sure how this could be utilized.
