Hello,
the Autodesk Advance Steel 2020 have a new feature called "Joint propagation" that it clone the same connection when AS find the same profiles, with the same model role...and nothing else. In this way I need 1 milion different model roles, in order to work.
In the current situation, if we have some profiles with the same sections and model roles, but with different materials, the command works the same!
It seems that the unique case that it doesn't work is when you already have a joint in the same position.
In my opinion, all feature needs to be considered like the Numbering.
In this way I can use correctly the standard model roles, but with several Lot/Phase or other attributes.
Thanks.
