Reinforcement

Description

The Reinforcement BarShapeCutList tool allows the user to create the rebar shape cut list of reinforcing bars.

This tool is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager.

Rebar Shape Cut List of reinforcing bars

Usage

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

Scripting

The Reinforcement BarShapeCutList tool can be used in macros and from the Python console by using the following function:

) -> ElementTree.Element

• Generates and returns a rebar shape SVG element for the given rebar object.
• rebar object can be of type <ArchRebar._Rebar> or <rebar2.BaseRebar>, to generate its shape svg.
• view_direction specifies the viewpoint direction for rebar shape. It can be of type FreeCAD.Vector or WorkingPlane.Plane though WorkingPlane.Plane is preferred.
• include_mark specifies if rebar.Mark is to be included in rebar shape SVG or not.
• stirrup_extended_edge_offset is 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_width specifies the stroke-width of rebar in svg.
• rebar_color_style specifies 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_dimensions specifies if each rebar edge dimensions and bent angle dimensions are to be included in rebar shape SVG.
• rebar_dimension_units specifies the units to be used for rebar length dimensions.
• rebar_length_dimension_precision specifies 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.
• include_units_in_dimension_label specifies if rebar length units is to be shown in dimension label.
• bent_angle_dimension_exclude_list specifies the list of bent angles to not include their dimensions.
• dimension_font_family specifies the font-family of dimension text.

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

• scale specifies 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_height specifies the maximum height of rebar shape SVG. Set it to 0 to have rebar shape SVG height based on the scale parameter.
• max_width specifies the maximum width of rebar shape SVG. Set it to 0 to have rebar shape SVG width based on the scale parameter.
• side_padding specifies the padding on each side of the rebar shape.
• horizontal_shape specifies if the rebar shape is to be made horizontal by rotating the max length edge of the rebar shape.
