Rectangular (closed) stirrup

After clicking , the following dialog displays:

To define a bar, the following should be specified:

Bar diameter (the diameter defined in the dialog is adopted by default)
Cover of a reinforcing bar (the cover defined in the dialog is adopted by default)
In the Parameters of reinforcing bar shape field - anchor parameters for bar ends, that is 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.

The shape of a bar presented in a schematic drawing is adjusted dynamically to the specified values of a hook bending angle. Standard hook angle values include:

0°
90°
135°
180°
-90°
-135°
-180°.

The following icons display in the dialog when a rectangular stirrup is defined (the remaining icons are unavailable):

Select - is used to indicate directly the contour formed from a polyline. After selecting, the dialog closes, and the cursor assumes the shape of a square (see the ACAD command ‘copy’ - phase of selecting the object to be copied). After selecting any point on the screen, the ACAD object is detected, and the transversal reinforcement (stirrup) is drawn within the indicated object
Diagonal - is used to create a rectangular contour by defining a diagonal. After selecting, the dialog closes, and while the cursor is moved, a defined rectangular stirrup is presented dynamically
Pick point - is used to search a closed contour by clicking inside the contour. After selecting, the dialog closes, and the cursor assumes the shape of a cross (see the ACAD command ‘hatch’). After selecting any point on the screen, the minimum closed contour is detected. The detected contour is changed to a stirrup shaped like the detected contour, but decreased by the cover value.

The Select and Pick point options apply to all figure types.

Once the stirrup shape is defined initially, a question displays regarding the places where hooks are to be located. They may be selected by indicating a stirrup corner.
