My model is located in Melbourne (UTC +10)and i am following the shadow chart as attached. we always use this chart while drawing shadow diagrams on 2D models in Cad, however we found that the shadows that are shown on the sketchup model does not match up.

Funny thing is considering the shadows in the previous image i attached are captured at the same day and coordinates, only the 9am one seems to go wrong while the other two are close enough.

I was wondering if this is the possibility of Sketchup having a bug. Or is there any 'Horizontal Shadow Angle' settings or similar that i can play around with to get the accurate angle.
