Dear, Thomas Fink.
From my point of view and experience the benefits of this feature are too high. I do not need use this functionality for all length of column.
For example in my previous project I had 35 types of reinforced concrete columns out of 40. I used peikko PCs corbel system to support beams. If you open this catalog you will find there on the pages 29, 30, 31, 33, 34 the "Annex A-Supplementary reinforcement". It was realy hard to copy stirraps along the column because some of them just axidently change the restriction. I always place them like it have to be ("Edit Constraince" or "Edit Sketch" ) after copying.
It would be much easier to implement my reinforcment job in case I have in Revit more rebar destributing types (as here it is said "by formula").
Thank you.
