Place rebar with 3D rotated hooks or cranks or rotate the hooks or cranks of existing bars. When you rotate the hooks or cranks at the ends of rebar, a 3D rebar shape is created, if the bar, hook and crank segments are no longer in the same plane.
The bar shape will be matched to an existing shape with similar rotation or a new shape will be created at various hook rotation intervals. Free form bars can also match to rebar shapes with rotate hooks/cranks, ensuring that fabrication data can be extracted for such bars.
- In the Structure tab
Reinforcement panel click the arrow and select Reinforcement Settings.
- In the Reinforcement Settings dialog General Reinforcement Settings, check the box for Include hooks in Rebar Shape definition.
These 3D shapes, as well as the existing multi-planar bars are displayed in plan and isometric views, in the rebar shape browser or when changing the shape of an existing bar.
You can choose the desired shape during rebar placement, as well as when changing the shape of an existing bar.
Hook or Crank Rotation, Rebar Shapes, and Numbering
Hook and crank rotation is taken into account when you define a rebar shape. For this, hooks need to be included in the rebar shape definition, by toggling the option in Reinforcement Settings, while cranks are always defining the rebar shape.
Rebar numbering compares the rebar shape, segment lengths, hook or crank rotation to determine the number for each bar.
In the simple case of a straight bar, identical rotations will keep the hooks/cranks in the same plane and match to a rebar shape with 0-degree rotation (standard shapes in the library).
If the hooks or cranks have different rotations - they are not in the same plane, a new shape is created for each 15-degree interval.
In the following example, the two bars have the same rebar shape because the rotation angle of the hook at start is in the same 15-degree interval. The rebar numbers are different because the hook rotations are different (40 and 45 degrees)

| Shape | 02 | 02 | Rebar Shape 1 | Rebar Shape 1 |
| Hook Rotation at Start | 0° | 230° | 40° | 45° |
| Hook Rotation at End | 0° | 230° | 90° | 90° |
Override Hook or Crank Lengths by Instance
Toggle the Override Hook Lengths or Override Crank Lengths option in the properties palette or in a rebar schedule to edit the lengths of hooks or cranks directly for each rebar instance. This is applicable for any rebar with hooks or cranks and requires that the hook or crank lengths be assigned to a rebar shape parameter.
You can edit the segment lengths in the properties palette, in a schedule or directly in canvas by clicking any of the values.
Path Reinforcement and 3D Hooks
Use rebar shapes with 3D hooks inside path reinforcement, to distribute rebar standees in the project.
