When I import a 3D near shading scene from Helios3D, PVsyst (version 6.72) changes the azimuth angle from 0° to 1°. I can manually change it back to 0° in the Orientations menu and Near Shadings menu, but when I run the simulation again, PVsyst changes it back to 1°. I am assuming that this is a cosmetic issue in PVsyst and the actual calculations are not affected since the shading table appears to be the same, however, need confirmation that this is the case.
