I have 2 C channels that are wrapping around a column.  When I have the Web of the C channel pointing out away from the column the beam join works perfectly.  When I flip the C channel so that the Web sits flush with the column it breaks the join and I cant get it to join back again.  In the picture from left to right- The beam join working correctly with the web facing out (not what I want), the second is the C channel flipped the correct way (still joined) but I have the column off of the beam, and the third is the C channel the correct way after I aligned the C channels to the column (tried aligning the Column to the C channel also with same result) and it breaks apart.  Any ideas?!

Not sure if you still have an interest in this question, but what I think is happening is that when the channel webs are flush to the column, Revit thinks that they are attaching to the column. This is similar to when you have 2 W beams intersecting over a column - the beam join tool won't work in this configuration. When you mirror the channel webs such that they are not flush to the column (or move the W beams such that they are not over the top of the column) and have them intersect again, you should get the error warning that tells you that the elements need to be unjoined (Revit should highlight the beam and the column at this point). Once the beams are all unjoined from the column, the beam join tool will work again. The Revit error warning and the fact it highlights those elements are my clues that this is the reason why the beam join tool won't work when the beams are seen as joined to the column. Hope that makes sense.
