Cranks refer to crank-shaped bends and they can be created with rebar set end detail modifiers or rebar set splitters.

(in below image you could see the red temporary line).
Base on the temporary line you can see the outcome of the application. If the outcome is ok then you can proceed otherwise you can change the options (Crank direction, Crank side, etc.) and try preview again. To clear the temporary line please update the window.

8) Click the button 'Modify'
Now the crank bar get modified accordingly.


Due to the rebar limitations sometimes the rebar location or the hook orientations can be disturbed. Please review the cranked rebar after applying this extension.
