Reinforcement Bar Shape Cut List

Description

The Rebar Shape Cut List tool allows the user to create the rebar shape cut list of reinforcing bars.

This command is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager via the Tools → Addon manager → Reinforcement menu.

Rebar Shape Cut List of reinforcing bars

Usage

1. Select Arch Rebar and Rebar2 objects you want to include in Rebar Shape Cut List. Or select Arch Structure objects to include Arch Rebar and Rebar2 objects hosted by that into Rebar Shape Cut List. If nothing is selected, then Rebar Shape Cut List will be generated for all Arch Rebar and Rebar2 objects present in the model.

2. Then select Rebar Shape Cut List from the rebar tools.

3. A dialog box will pop-out on the screen as shown below.

Dialog Box for the Reinforcement Bar Shape Cut List tool

4. Modify data to suit your requirements.

5. Click OK or Apply to generate Rebar Shape Cut List for rebars.

6. Click Cancel to exit the dialog box.

Properties

General:

  • Stirrup Extended Edge Offset: The offset of extended end edges of the stirrup, so that end edges of the stirrup with a 90-degree bent angle do not overlap with stirrup edges.

  • Rebars Stroke Width: The stroke-width of rebars in the rebar shape cut list.

  • Rebars Color Style: The color style of rebars.

  • Row Height: The height of each row of rebar shape in the rebar shape cut list.

  • Column Width: The width of each column of rebar shape in the rebar shape cut list.

  • Column Count: The number of columns in the rebar shape cut list.

  • Side Padding: The padding on each side of the rebar shape.

  • Horizontal Rebar Shape: If True, then the rebar shape will be made horizontal by rotating the max length edge of the rebar shape.

  • Include Mark: If it is set to True, then rebar.Mark will be included for each rebar shape in the rebar shape cut list.

  • SVG Output File: The output file to write generated rebar shape cut list SVG.

Dimension Data:

  • Include Dimensions: If True, then each rebar edge dimensions and bent angle dimensions will be included in the rebar shape cut list.

  • Include Units in Dimension Label: If it is True, then rebar edge length units will be shown in dimension label.

  • Rebar Edge Dimension Units: The units to be used for rebar edge length dimensions.

  • Rebar Edge Dimension Precision: The number of decimals that should be shown for rebar edge length as a dimension label.

  • Dimension Font Family: The font-family of dimension text.

  • Dimension Font Size: The font-size of dimension text.

  • Bent Angle Dimension Exclude List: The list of bent angles to not include their dimensions.

  • Helical Rebar Dimension Label Format: The format of the helical rebar dimension label. e.g. "%L,r=%R,pitch=%P" where %L -> Length of helical rebar, %R -> Helix radius of helical rebar, %P -> Helix pitch of helical rebar.

Scripting

The Rebar Shape Cut List tool can be used in macros and from the Python console by using the following function:

Create Rebar Shape SVG

getRebarShapeSVG(
    rebar,
    view_direction: Union[FreeCAD.Vector, WorkingPlane.Plane] = FreeCAD.Vector(0, 0, 0),
    include_mark: bool = True,

) -> ElementTree.Element

  • Generates and returns a rebar shape SVG element for the given rebar object.

  • rebarobject can be of type <ArchRebar._Rebar> or <rebar2.BaseRebar>, to generate its shape svg.

  • view_directionspecifies the viewpoint direction for rebar shape. It can be of type FreeCAD.Vector or WorkingPlane.Plane though WorkingPlane.Plane is preferred.

  • include_markspecifies if rebar.Mark is to be included in rebar shape SVG or not.

  • stirrup_extended_edge_offsetis the offset of extended end edges of the stirrup, so that end edges of the stirrup with a 90-degree bent angle do not overlap with stirrup edges.

  • rebar_stroke_widthspecifies the stroke-width of rebar in svg.

  • rebar_color_stylespecifies the color style of rebar. It can be "shape color" or "color_name or hex_value_of_color". "shape color" means to select the color of the rebar shape.

  • include_dimensionsspecifies if each rebar edge dimensions and bent angle dimensions are to be included in rebar shape SVG.

  • rebar_dimension_unitsspecifies the units to be used for rebar length dimensions.

  • rebar_length_dimension_precisionspecifies the number of decimals that should be shown for rebar length as a dimension label. Set it to None to use user preferred unit precision from FreeCAD unit preferences.

   %L -> Length of helical rebar    %R -> Helix radius of helical rebar    %P -> Helix pitch of helical rebar

  • scalespecifies the scale value to scale rebar SVG. The scale parameter helps to scale down rebar_stroke_width and dimension_font_size to make them resolution-independent. If max_height or max_width is set to a non-zero value, then the scale parameter will be ignored.

  • max_heightspecifies the maximum height of rebar shape SVG. Set it to 0 to have rebar shape SVG height based on the scale parameter.

  • max_widthspecifies the maximum width of rebar shape SVG. Set it to 0 to have rebar shape SVG width based on the scale parameter.

  • side_paddingspecifies the padding on each side of the rebar shape.

  • horizontal_shapespecifies if the rebar shape is to be made horizontal by rotating the max length edge of the rebar shape.
