Net perimeter listed in the zone list.

[elisb]

Hello,

How can I list the net perimeter of a zone (total perimeter - doors width) ? 

Thank you.

You can define new Property by using classification and properties in which write expression for length type, deduct door widths from Zone Gross perimeter. ( Zone Net perimeter can be used only if wall lengths are considered for calculation. Refer AC help for better understanding )
