I suppose a picture would be worth 1000 words ...
The first one is a scenario which I find myself needing to accomplish regularly, particularly when dealing with multiple plane roof sections with multiple pitches.
The second one is my workaround to find the point. It would be nice if there were an implied intersection or a defacto intersection where the edges of the 2 planes cross, but alas there is not ... or rather I have not yet found it ... if you could give me a better solution then I would be tremendously thankful.
