[Equest-users] User Expression for Infiltration Neutral Zone Height

[Melissa Crowe]

Hi All

Help please, I am struggling with User Expression that calculates the Neutral Zone Height for high rise infiltration. It's something like:

((Parent("Z")-0)+Local("Height")/2)*-1+(BH/2 - BG)

Where:
BH = Building Height
BG = Total of Below Grade FL to FL Height

Also the default expression includes  a switch statement.  I don't thin I need a switch statement, so how is it formatted?
