<p class="MsoNormal">Hi All<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Help please, I am struggling with User Expression that calculates the Neutral Zone Height for high rise infiltration. It’s something like:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">((Parent("Z")-0)+Local("Height")/2)*-1+(BH/2 - BG)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Where:<o:p></o:p></p>
<p class="MsoNormal">BH = Building Height<o:p></o:p></p>
<p class="MsoNormal">BG = Total of Below Grade FL to FL Height<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also the default expression includes a switch statement. I don’t thin I need a switch statement, so how is it formatted?<o:p></o:p></p>
