When I do "shading & insolation" I get message: <br>Zone Shading & Insolation db mismatch with current model.<br>Model NSUR =  6 db NSUR =  0 db last record =  0<br>I have checked that my surfaces have correct vertices, starting from bottom left and go anticlockwise. I have no problem running the example "building with shading".<br>However; I have problem with a simpler model, my model.
