Parametric Rebar Cranking (What's New in 2026)

Easily model cranked rebar in congested areas to prevent clashes.

  • You can propagate rebar with cranks to similar concrete elements.
  • Like hooks, the crank is a parametric termination of the bar.
  • You can add cranks to shape driven and free-form rebar.The presence of the crank defines the shape, either matching to an existing one or creating a new shape.
  • The crank is added within the length of the segment for both shape-driven and free-form rebar.
  • Editing constraints of bars with crank: For each cranked bar end, there are three handle positions from which the offset is measured:

  • Crank and hook rotation: Crank rotation is applied to all bars in the set and defines the rebar shape. Rotate individual bars using Edit Bars. For free-form rebar, the crank default rotation (0 deg) is perpendicular to the host surface.

  • Crank dimensions and override by type: Duplicate an existing crank type to create your own. Override the values of crank slope and lengths for the rebar type. See Rebar Crank Length Parameters.
  • Reporting cranked rebar lengths and editing the rebar shape family:
    • Control the assignment of hooks, end treatments and cranks from the Type At Start / Type At End parameters in the rebar shape family.
    • Use the new Shape Name parameter to report the shape code for cranked bars and sketched bars. The parameter is editable from the shape family.
    • Add the start / end crank lengths to the rebar shape parameters for reporting in the model.
    • Shape Name is read-only in the model.

This feature was suggested by customers on the Ideas forum and is described on the product road map.
