The Shapes tab allows you to select the shape of reinforcement.
Select RC Design Provided reinforcement layout, and then create a new RC element or open an existing one.
Specify the shape for the following bars: Main bar, Dowel bar, Stirrup, Open stirrup, Splice bar, Circular stirrup.
Specify the hook length for each bar.
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.
The Save As option allows you to reuse a set of reinforcement pattern parameters. This set is saved to your current user directory. You can reuse this set for the other element in the Reinforcement Pattern dialog or assign it to the selected element (or selected elements of the same type) in the RC Component Inspector.
The Delete option allows you to remove the selected set of reinforcement pattern parameters.
