A reinforcement drawing shows the positions of all reinforcing elements in a particular structure or a structural element. There are numerous ways of drafting concrete shop drawings, and drafting styles vary between countries or even between design companies.
Rebar in Revit comes with properties that can be read by predefined tags (families) created specifically to read the rebar settings. It’s possible to let Revit tag these items automatically, or you can manually tag the items.
Multi-rebar annotations significantly improve rebar detailing workflow. A multi-rebar annotation allows you to tag multiple rebar and rebar sets with a single annotation.
You can use these multi-rebar annotations to tag each bar in a rebar set with a detailed annotation for fabrication and construction. Thanks to this functionality, drawing creation becomes quite smooth and productivity increases incomparably.
If you want to use this functionality in Revit you need to go on the Annotate tab -> Tag panel and under Multi-Rebar you can find the following two tools:
- Aligned Multi-Rebar Annotation
- Linear Multi-Rebar Annotation
Once you run one of them then you simply select rebar sets or individual rebars to have them annotated by one single annotation. You can also modify multi-rebar annotations like other tags.
A Multi-rebar annotation family is a Revit system family. In the Type Properties you can find a tag family and a dimension style that can be easy configured and adjusted.
