The crank is added within the length of the segment for both 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.
In the following example, a crank is added at the start of the bar (1) and the angled length B is overridden to 400 mm (2).
During placement, the crank is maintained within the length of the segment and does not exceed the concrete cover. The following example shows the placement of a straight bar with crank using the expand to host method (A), and the placement of an L-bar with crank on the end using the placement by two points (B).
