Hi Olympia,

Rotating the North vector in SimCad is one way of turning the building.

If you have trouble using it, there's a much simpler way though (that I 
personaly prefere):
Go to Preference/TRNSYS parameters and click on "Quick calculation".
In the editor "Turn Building by" you can directly specify an angle by 
which you
want to turn the building (clockwise).

The advantage of this method is that SimCad writes an equation for 
turning the
building to the deck (instead of redefining all orientations).
You can find this equation later in IISiBat under Global Cards in the 
Simulation
Cards editor (there's an equation called TURN=..., where ... is the 
angle) and
continue to turn the building even in IISiBat.

Happy turning,

Werner
