<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica",sans-serif;color:black">Our project is considering a dome roof for a multi-purpose space as part of a mall development. I tried drawing the dome in sketchup/openstudio and exported
as gbXML which I imported in HAP. Since HAP only imports up to a maximum of 4 roof surfaces via gbXML, adjustments in the imported roof surface areas need to be made as suggested in the built-in Help. I am not sure this will be accurate considering the orientations
and slopes of the surfaces that will be combined so that there are only 4 roof surfaces for the space. Any suggested workflow or work around will be highly appreciated. Thank you.<o:p></o:p></span></p>
