Footing UShapeRebar.png


  1. Select any face of a previously created Arch Structure.svg Arch Structure object.
  2. Then select Arch Rebar UShape.svg UShape Rebar from the rebar tools.
  3. A task panel will pop-out on the left side of the screen as shown below.
  4. Select the desired orientation.
  5. Give the inputs like front cover, right side cover, left side cover, bottom cover, top cover, rounding factor and diameter of the rebar.
  6. Select the mode of distribution either amount or spacing.
  7. If spacing is selected, a user can also opt for custom spacing.
  8. Pick selected face is used to verify or change the face for rebar distribution.
  9. Click OK or Apply to generate the rebars.
  10. Click Cancel to exit the task panel.


Taskview panel for the Arch Rebar UShape tool


  • DataOrientation: It decides the orientation of the rebar (like a bottom, top, right and left).
  • DataFront Cover: The distance between rebar and selected face.
  • DataRight Cover: The distance between the right end of the rebar to right face of the structure.
  • DataLeft Cover: The distance between the left end of the rebar to the left face of the structure.
  • DataBottom Cover: The distance between rebar from the bottom face of the structure.
  • DataTop Cover: The distance between rebar from the top face of the structure.
  • DataRounding: A rounding value to be applied to the corners of the bars, expressed in times the diameter.
  • DataAmount: The amount of rebars.
  • DataSpacing: The distance between the axes of each bar.


Инструмент UShapeRebar.png UShape Rebar можно использовать в macros и на консоли python с помощью следующей функции:

Rebar = makeUShapeRebar(f_cover, b_cover, r_cover, l_cover,
                        diameter, t_cover, rounding, amount_spacing_check, amount_spacing_value, orientation="Bottom",
                        structure=None, facename=None)
  • Creates a Rebar 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.
  • f_cover, b_cover, r_cover, l_cover, and t_cover are inner offset distances for the rebar elements with respect to the faces of the structure. They are respectively the front, bottom, right, left, and top offsets.
  • diameter is the diameter of the reinforcement bars inside the structure.
  • rounding is the parameter that determines the bending radius of the reinforcement bars.
  • amount_spacing_check if it is True it will create as many reinforcement bars as given by amount_spacing_value; if it is False it will create reinforcement bars separated by the numerical value of amount_spacing_value.
  • amount_spacing_value specifies the number of reinforcement bars, or the value of the separation between them, depending on amount_spacing_check.
  • orientation specifies the orientation of the rebar; it can be "Bottom", "Top", "Right", or "Left".

Пример: Создание U Shaped арматуры.

import FreeCAD, Arch, UShapeRebar

Structure = Arch.makeStructure(length=1000, width=1000, height=400)
Structure.ViewObject.Transparency = 80

Rebar = UShapeRebar.makeUShapeRebar(50, 20, 20, 20,
                                    8, 50, 4, True, 6, "Bottom", Structure, "Face4")
Rebar.ViewObject.ShapeColor = (0.9, 0.0, 0.0)

Rebar2 = UShapeRebar.makeUShapeRebar(50, 50, 20, 20,
                                     8, 50, 4, True, 6, "Bottom", Structure, "Face6")

Изменение свойств арматуры UShape.

editUShapeRebar(Rebar, f_cover, b_cover, r_cover, l_cover,
                diameter, t_cover, rounding, amount_spacing_check, amount_spacing_value, orientation,
                structure=None, facename=None)
  • Rebar is a previously created UShapeRebar object.
  • The other parameters are the same as required by the makeUShapeRebar() function.
  • structure and facename may be omitted so that the rebar stays in the original structure.
