FWIW - I was just going to answer that CW is clockwise but instead thought I’d tried the instructions.
Attached are the results - 2 because as far as I know, CW is -45º and CCW is 45º but then you would have to make a 2D from the BACK view. As base point, I picked a point on the right edge of the sloping wall where it meets the roof - not visible from the back view.
