Create complex rebar designs in BIM models with Revit

Autodesk Support

Aug 1, 2018


What

Use dedicated tools in Revit to create detailed complex rebar designs in BIM models.
 

Who

Structural designers, Rebar detailers.
 

How

Improve scheduling and annotation of rebar in your documentation. In Revit 2019, free form rebar now matches existing rebar shape families or creates families with a matching shape.

Revit does this matching for each bar in the set individually, extracting fabrication data such as individual bar segment lengths and hooks. The geometry of free form rebar is defined by the selected references and matched to a rebar shape family.

Use the Workshop Instructions parameter to specify how free form rebar is fabricated:

  • Straight. The bar is delivered as a straight bar to the site, and the shape code is the first straight rebar shape loaded into the project, like 00.
  • Bend. The bar is matched to an existing rebar shape if possible. Otherwise, a matching bar is created.

Free form bars are matched to a rebar shape family. Rebar numbering, assemblies, and other properties in the structural rebar category use the shape information (shape codes and segment lengths).

Learn how to use these customization tools. See Free-form Rebar Shape Matching.
 

Why

Enhance the 3D model and bar bending schedules to show individual segment lengths and shape codes when using planar free form rebar.
 

What next?

  • Document the designs in Revit.
  • Extract digital data from the model for reuse in other systems and for fabrication deliverables.
