Select the Analysis menu > Reinforcement Pattern and open the Shapes tab. The following dialog displays.
Options in this dialog let you select shapes of the longitudinal and transversal reinforcement. For cross bars, the pin or stirrup shape is selected. For transversal bars you can select a preferred shape of a stirrup, pin or transport handle. The longitudinal bar shape (ends) are set in a similar way with differentiation between main and structure bars. You can select the end type for each end of the bar in the shape of a hook, bent at any angle.
The Hooks only if necessary option refers to bars ending with hooks. Select it to automatically select a bar end type based on that if the bar anchorage is required. For example, the main bar, no. 2.02 - with hooks on its 2 ends, after generating the beam reinforcement can be replaced with bar no. 1.02 (hook on one end) or with a straight bar.
Additionally, you can use the option that defines the length of a hook, by specifying its length, or by making its length dependent on the bar diameter.
