Round Window Area

[Velocipede2022]

How do do I get archiCAD to tell me the area of a window, a round window? This 5ft x 5ft window does not have an area of 25sf, it should be about 19.6sf.   Seem like this information should be somewhere in the BIM model?

Thanks, 

Operating system used: Windows

If your label (text) is simply multiplying the width by the height, then that is the correct value based on that, but the wrong calculation for a round window.

Does your window have a parameter that shows the area?

If so you can use that.

If not you can create a property with an expression and do the correct area calculation in that expression.

Then use the property to show the correct area.
