Determine the following information (concerning the reinforcing bar): diameter, cover, parameters of a bent bar ending with hooks, i.e. hook angle and length at the beginning and end of a reinforcing bar
Determine the angle of the bar bending (the following values of a bending angle are available: 30, 45 and 60 degrees)
Click (Diagonal), on the right side of the dialog
Determine the bar points beginning and end positions
Determine the length (position) of the bent part of a reinforcing bar.
