Once any of the transport reinforcement types is selected, the Special reinforcement dialog displays:
To define a bar, the following should be specified:
- Bar diameter (the diameter defined in the dialog is adopted by default)
- Reinforcing bar cover (the cover defined in the dialog is adopted by default)
- In the Shape parameters field -anchorage parameters for reinforcing bar ends, i.e. hook angle and length; you can lock a hook length by selecting the option next to the edit field for defining a hook length (
appears). The edit field becomes inaccessible. If you modify parameters (length or diameter) of a bar with locked hook length, the hook length does not change.
While defining this reinforcement type, only one icon 
(Points) is available in the dialog. After selecting this icon, the dialog closes, and the cursor assumes the shape of a cross (see the ACAD command 'line'). During definition of transport reinforcement, the user should specify three or four snap points of this reinforcement type.
Command line:
Select bar attachment point
Select second bar point
Select bar node
If need be, fourth point
Cover / Side / Mirror
where:
first (attachment point), second, third and if need be, fourth reinforcement snap point
cover - determines a cover value for each segment of reinforcement separately
side - changes reinforcement position with respect to an object (formwork)
mirror - mirror reflection of the defined reinforcement with respect to the first segment of reinforcement
