The rebar coupler size automatically adjusts to match the bars you are trying to connect, or it reacts to the changes in size you make to already connected bars.
A matching coupler type is selected from the same family, if it exists, or from another family loaded in the project. If a matching coupler type does not exist in the project, a new coupler type is created.
Couplers are no longer deleted when they do not match the connected rebar. You can quickly place couplers between bars of different diameters without errors.
