I just started testing Grasshopper-ARCHICAD Connection and it looks very promising. I have two questions concerning ARCHICAD Wall and Window orientations in Grasshopper:
1- What exactly controls the outside/inside direction of ARCHICAD walls that we create in Grasshopper? I ask this because when I use the Wall tool and Wall Settings tool to create composite brick walls from closed polylines, and when I draw polylines in a counter-clockwise fashion, the brick finish face is created on the outside of the polyline loop, but when I draw the polylines in a clockwise fashion, the brick is created on the inside of the loop. How can we control the outside/inside direction when creating walls? I did not find any information on this.
2- Why do we have to specify an orientation point in the Orientation input when creating windows? Can’t we just automatically orient the windows towards the outside/inside direction of the host wall? I am not sure if this was the case before, because the 2.3 User Guide on page 39 shows the Window tool without an Orientation input.
I hope this community can shed light on these two questions.

Thank you for your answer. It makes a lot of sense now.
However, I have been trying to create a parametric definition in Grasshopper where I automatically orient the windows to the outside by projecting the insertion points on the offset curve of the wall. But I receive this error message: "Invalid Orientation value. The Orientation point cannot lie on the vertical plane that contains the Insertion Point and is perpendicular to the Wall Reference line."
So I found a workaround where I nudge (move) these offset points very slightly with an XYZ vector. It works fine, but I wish there was a more straightforward way. I am still confused about this error message and why my solution actually worked.
