    Hey Benjy,

    thanks a lot for this mindboggling rundown of your struggles, but even more so for the solution!

    I never approached it like that, to exclude the offending spot and its cameras and only add them at the end. Very interesting and certainly good advice for people who get stuck with similar situations.

    Funny, this reminds me of doing old fashioned building measured surveys, which are always more about drawing out the individual rooms incl diagonals etc, coupling them together via doorways and assuming intervening walls (and floors) are parallel-thickness; the exterior (by running measurements) is almost an afterthought!

    But sometimes things just won't join up satisfactorily and it can make sense to draw the 'Components' that do work well, and try to jam them together at the end.

    That way, errors get concentrated in a small 'danger zone' where the Components abut, where you know dimensions scaled from the plan are suspect (and re-measurement can help), but at least scaling is safe everywhere else.

    I'm noticing I'm not getting alerts with responses over the forum, anybody else experiencing that?

    Anyway, thanks for the feedback. It's right to question why the long description, why not just cut to the chase in describing the fix? What I learned in so much trial and error and what I thought valuable to share is how all these behaviors, CPs with high projection errors, alignment settings, active/inactive states of various selections of cameras, etc. how all of this comes into play, something that quickly has you chasing your tail, or only improving the whole at the edges, but never getting to the heart of the matter. In my case, I had a core problem barring the merging of these two components. Only when I ran out of things to keep me busy chipping away at the edges of the problem was I forced to confront this core problem, merging any part of A to any part of B. There was nothing in the point cloud like a separated surface to provide a clue, the max projection error fell within acceptable value , the default 2.0, so the deformity in A or B or both remained hidden. the take home there was truly a fishing expedition to see what combination of activated cameras isolated against those cameras introducing the deformation. The workflow used to address the separation, a bad loop closure (?) was then icing on the cake. So, there you have it, a toofer, a lengthy explanation to my lengthy explanation ;^)
