    right_rebars_hook_extension=40,
    right_rebars_hook_orientation="Front Inside",
    structure=None,
    facename=None,
)

Creates a RebarGroup object from the given structure, which is an Arch Structure, and facename, which is a face of that structure.
- If no structure nor facename are given, it will take the user selected face as input.
l_cover_of_stirrup, r_cover_of_stirrup, t_cover_of_stirrup, b_cover_of_stirrup and offset_of_stirrup are inner offset distances for the stirrup elements with respect to the faces of the structure. They are respectively the left, right, top, bottom and front/rear offsets.
bent_angle define the angle of the tip of the reinforcement loop of stirrup.
extension_factor define the length of the tip of the reinforcement loop of stirrup, expressed in times the diameter.
dia_of_stirrup is the diameter of the stirrup.
number_spacing_check if it is True it will create as many stirrup as given by number_spacing_value; if it is False it will create stirrup separated by the numerical value of number_spacing_value.
number_spacing_value specifies the number of stirrups, or the value of the separation between them, depending on number_spacing_check.
top_reinforcement_number_diameter_offset and bottom_reinforcement_number_diameter_offset are tuple of number_diameter_offset string. Each element of tuple represents reinforcement for each new layer.

   Syntax: (
               "number1#diameter1@offset1+number2#diameter2@offset2+...",
               "number3#diameter3@offset3+number4#diameter4@offset4+...",

      layers.

          ('<rebar_type>', '<rebar_type>', ...),

      ]
      each element of list is a tuple, which specifies rebar type of each reinforcement layer. And each element of
      tuple represents rabar_type for each set of rebars.
   4. [
          <rebar_type>,
          ('<rebar_type>', '<rebar_type>', ...),
          ...,

top_reinforcement_layer_spacing and bottom_reinforcement_layer_spacing is the spacing between two consecutive reinforcement layers.

   Possible values:
   1. <layer_spacing>
   2. (<spacing in layer1 and layer2>, <spacing in layer2 and layer3>, ...) and number of elements of tuple must be
      equal to one less than number of layers.

left_rebars_number_diameter_offset and right_rebars_number_diameter_offset are string of number_diameter_offset.

   Syntax: "number1#diameter1@offset1+number2#diameter2@offset2+..."

left_rebars_type and right_rebars_type specifies type of left/right reinforcement bars.

left_rebars_spacing and right_rebars_spacing is clear spacing between consecutive reinforcement bars.
top_reinforcement_l_rebar_rounding and bottom_reinforcement_l_rebar_rounding is the parameter that determines the bending radius of the LShaped top/bottom rebars, expressed as times the diameter. Possible syntax are similar to as discussed above for top_reinforcement_rebar_type / bottom_reinforcement_rebar_type.
top_reinforcement_hook_extension and bottom_reinforcement_hook_extension is the length of hook of LShaped rebars. Possible syntax are similar to as discussed above for top_reinforcement_rebar_type / bottom_reinforcement_rebar_type.
top_reinforcement_hook_orientation and bottom_reinforcement_hook_orientation specifies the orientation of LShaped hook; it can be "Front Inside", "Front Outside", "Rear Inside" or "Rear Outside". Possible syntax are similar to as discussed above for top_reinforcement_rebar_type / bottom_reinforcement_rebar_type.
left_l_rebar_rounding and right_l_rebar_rounding is the parameter that determines the bending radius of the LShaped left/right rebars, expressed as times the diameter. Possible syntax are similar to as discussed above for left_rebars_type / right_rebars_type.
left_rebars_hook_extension and right_rebars_hook_extension is the length of hook of LShaped rebars. Possible syntax are similar to as discussed above for left_rebars_type / right_rebars_type.
left_rebars_hook_orientation and right_rebars_hook_orientation specifies the orientation of LShaped hook; it can be "Front Inside", "Front Outside", "Rear Inside" or "Rear Outside". Possible syntax are similar to as discussed above for left_rebars_type / right_rebars_type.
