Select the Openings tab in the Reinforcement: definition and detailing dialog to display the following options.
Use this dialog to specify parameters for bar ends near openings. The same end types as for other bars are available for bars that adjoin to openings (see the Shape tab).
If reinforcing bars pass through an opening, they are divided into 2 parts (on 2 sides of the opening). You can define an end type for each part of a divided bar; thus bar ends on both sides of the opening may differ.
Note that a bar may adjoin to the opening with one end and with the other - to the slab edge; ends of such bar are defined on 2 tabs (Openings and Shape) then.
