This palette allows you to site live updates as you edit your building.
You can enter the Maximum FAR and Building Coverage values in the Project settings.
The horizontal bar charts change colour - green up to 95%, amber 95% -100% and red when you are over the allowable values.
Codesign Calculations provide the ability for you to define area based calculations. The default FAR calculation is used for all FAR based reports.
If the FAR Calculation is not present in the project then the gross area is used.
