angled gable windows - blocking

I'm working on a log home for a customer and its got this big gable wall, cathedral ceiling, and large angled windows. I'm having trouble mulling 2 angled windows together cleanly...see attached pictures, the full elevation shot is showing the windows seperated, and the close-up is showing them blocked.

I'm thinking the problem is the size of the windows themselves, i've tried to solve it geometrically but i've not yet been able to get the exterior trim to align properly once the 2 windows are blocked together.

any tips or tricks to make this work? or am i going to have to clean this up in CAD?

Do you have a lower wall and attic wall? If so, were both windows created in the same wall?

One other thing. It looks like there may be a problem with the lower window (on the left).

there is an attic wall but all the windows are drawn on the 2nd floor.

what problem?

Matthew, The only thoughts I could add: Is the Default Window set to a minimum separation of 0 and nothing under the Mfr. Offset (Casing Tab).
