The dimensions for linear multi-rebar annotations (MRAs) are aligned to the horizontal or vertical axis of the view.
To use multi-rebar annotations, there must be at least two rebar references. Like Linear Dimensions, Linear MRAs can only be placed on point references.

Multi-Rebar
(Linear Multi-Rebar Annotation). In the Type Selector, a Structural Rebar Multi-Rebar Annotations (MRA) type is enabled.
You can tag a single rebar set or multiple rebar sets with a single annotation. You can only place MRAs on rebar when the view direction is parallel to the plane of the rebar.
