With multi-rebar annotations, you can select multiple aligned rebar and display the dimensions between the rebar references, as well as parameter data.
The dimensions for aligned multi-rebar annotations display parallel to the tagged structural rebar references.
To use multi-rebar annotations, there must be at least two rebar references. Only references which would work for aligned dimensions can be selected.
In the Type Selector, a Structural Rebar Multi-Rebar Annotations type is enabled.
(Optional) You can create a new multi-rebar annotation type or modify an existing type. In the Properties palette, select Edit Type. Then select Duplicate, name the new type, make your changes and select OK.
You can tag a single rebar set or multiple rebar sets with a single annotation. You can only place multi-rebar annotations on rebar when the view direction is parallel to the plane of the rebar.
