area of an arched window

[umbachdw]

I have not been able to find this in my brief search so I thought I would just take the east way out and ask....

How do you get revit to report the area of an arched window?  Generally, the areas in my schedule are a calculation of width x height.  For a semicircular arch the formula would be fairly easy, but for other more complicated shapes it seems like Revit should be able to just report the area of the cut-out.  Is there a way to do that?

Thanks.

probably easiest way without getting into shared parameters, fixing/changing all window families, etc. is to create a material takeoff schedule and filter by glass.

That would work, but it would not give me the rough opening area that I need for energy code.  I can manage the math to calculate the area of the segmental arch, but I would need to add the parameters to the window family to provide the data.  I have been playing with it a bit and have had some trouble getting it to work.  May be easier just to crunch the numbers by hand - always hate to do that.

- add  a shared reporting parameter to report the wall thickness to the family

- create a solid in the window family that fill the opening volume, assign it with a special material

- load in project, create a material take-off schedule for that material

- add the same wall thickness shared parameter

- create a calculated value to get the area from the volume/thickness

Could you not create a calculated parameter in the window which multiples the square area of the window added to the semi-circle part which would be half of (Pi * radius) squared - that would calc the area...

This would work, provided that I can get all of the info together in a single schedule.  I have not had time to work on it yet.  It just seems like something that should be easier.  Revit already knows the total net area of the wall, it seems like having it report the area of one opening should be a built in function.  Anyway, I will give this a try.

Calculating that area of a 1/2 circle arch would be fairly easy.  Segmental arches are more complicated.  It could still be done if I could get the parameters working to report all of the data.
