<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hey everyone,<br>
<br>
When making a 3D Building project (multizone), I encountered an error when trying to open my .idf-model (google sketchup).
<br>
The error is the following:<br>
"At least 2 surfaces are required per zone!"<br>
<br>
What 's weird about this error, is that I can not find a zone consisting of less than 2 surfaces + I can't find "surface -1" in my model.<br>
<br>
I searched but have not been able to solve this error yet.<br>
Is anyone familiar with this error? Where lies the problem?<br>
You can find my .idf-model in annexe. <br>
<br>
Thank you very much for helping me out,<br>
<br>
