When you use the Generate Rotate command, the beta angles remains the same so you have to uptade member by member the new beta angle for the non-orthogonal elements that were affected. The idea is a custom tool that automatically creates the new beta angles and assign for all the affected members
Thank you for posting this idea. Have you make use of the Beam Reference Point?
I imagine you might have a node or define the point at the centre of your sweep as the origin, then if this is assigned to the member which you sweep with the Circular Repeat, then each generated member will also use this point to define the local axis Z. Here is an example where the highlighted member has been rotated about the origin and has node 1 as the reference point which is also applied to the 4 generated members:-
