Define and Add a Rebar Crank

For existing rebar in the project or during rebar placement, you can assign cranks to bar ends or change to a rebar shape that has a crank already assigned.

Rebar cranks are defined by the crank slope, offset and length multipliers.

Rebar cranks have a matrix relationship between the crank properties and rebar size. The rebar crank type comprises a defined crank slope, offset and length. If the existing cranks are appropriate, you can start this procedure at step 7.

1. In the Project Browser, navigate to FamiliesStructural RebarRebar Crank.
2. Right-click a crank, and select Duplicate.
3. Double-click the new copy.
4. Define the Crank Slope, Offset and Length Multipliers. See Rebar Crank Length Parameters.
5. Click OK.
6. Right-click the new crank type and select Rename. Enter a name for the crank type. You can now apply this crank type to rebar instances within the project, to get the desired bar geometry.
7. Select a rebar instance (which can be a single bar, or a rebar set), in a relevant view.
8. On the Properties palette, add a crank to the start or end, as needed under the Construction section:
   1. First select Crank in either the Start of Bar or End of Bar parameters.
   2. Then select the crank type for the Crank at Start or Crank at End parameter which become available after the previous step.
