I own a wholesale window and door distributorship which I inherited from my grandparents last summer.... which is why I haven't been around much since then... and I must admit that I'm having trouble following what you're trying to do, too. Actually, what it looks like you've got going is what we call a French door, two doors hinged at the jambs (sides) and locking together in the center. If this is the case, then in your image the corners of these doors (or window sashes) are touching while the doors themselves are at a right angle to each other (judging by the position of the knobs). I'd have to say, based on what I can see in your image, is simply to make each "side" of your window separately. Place the two sides together as if the window were closed. Then rotate eace "side" at the point where the hinges would be (can you move an objects "hot point" in Bryce?) to open them. Also, there would be some sort of projection on one of the "sides" which would overlap the outside of the opposite "side" when closed to prevent weather from getting in. Hope this helped some.
