Description

The Reinforcement Drawing tool allows the user to create drawing of reinforcing bars.

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

Drawing and dimensioning of reinforcing bars


Usage

1. Open FreeCAD Model containing reinforcement bars created using Reinforcement Addon.

2. In FreeCAD Python console, copy below code snippet to generate reinforcement drawing from different views for each Arch Structure element.

from ReinforcementDrawing.make_reinforcement_drawing import (
    makeStructuresReinforcementDrawing,
)

for view in ("Front", "Rear", "Left", "Right", "Top", "Bottom"):
    makeStructuresReinforcementDrawing(view=view)

ReinforcementDrawingView Object

A Rebars Drawing SVG View object.

Properties

  • DataStructure: The structure object acting as Host for rebars to be included in drawing.
  • DataRebars: The list of rebar objects to be included in drawing.
  • DataView: The reinforcement drawing view to be generated. It can be "Front", "Rear", "Left", "Right", "Top" or "Bottom".
  • DataPositionType: The position type of Reinforcement Drawing on Template. It can be "Automatic" to calculate drawing placement using DataLeftOffset, DataTopOffset, DataMinRightOffset and DataMinBottomOffset OR "Custom" to set placement using DataX and DataY.
  • DataRebarsStrokeWidth: The stroke width of rebars in Reinforcement Drawing svg.
  • DataRebarsColorStyle: The color style of rebars in Reinforcement Drawing svg. Set it to "Automatic" to automatically select rebars color OR "Custom" to choose shape color value from DataRebarsColor.
  • DataRebarsColor: The color of rebars in Reinforcement Drawing svg.
  • DataStructureStrokeWidth: The stroke width of structure in Reinforcement Drawing svg.
  • DataStructureColorStyle: The color style of structure in Reinforcement Drawing svg. Set it to "Automatic" to automatically select rebars color, "Custom" to choose shape color value from DataStructureColor OR "None" to not fill structure.
  • DataStructureColor: The color of structure in Reinforcement Drawing svg.
  • DataTemplate: The template for Reinforcement Drawing view.
  • DataWidth: The width of Reinforcement Drawing view svg.
  • DataHeight: The height of Reinforcement Drawing view svg.
  • DataLeftOffset: The left offset of Reinforcement Drawing view on template.
  • DataTopOffset: The top offset of Reinforcement Drawing view on template.
  • DataMinRightOffset: The minimum right offset of Reinforcement Drawing view on template.
  • DataMinBottomOffset: The minimum bottom offset of Reinforcement Drawing view on template.
  • DataMaxWidth: The maximum width of Reinforcement Drawing view.
  • DataMaxHeight: The maximum height of Reinforcement Drawing view.
  • DataVisibleRebars: The list of visible rebar objects in drawing view.
  • DataDimensionLeftOffset: The left offset for each new ReinforcementDimensioning object.
  • DataDimensionRightOffset: The right offset for each new ReinforcementDimensioning object.
  • DataDimensionTopOffset: The top offset for each new ReinforcementDimensioning object.
  • DataDimensionBottomOffset: The bottom offset for each new ReinforcementDimensioning object.

Scripting

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

Create Reinforcement Drawing View

For one structure

from ReinforcementDrawing.make_reinforcement_drawing import (
    makeReinforcementDrawing,
)

reinforcement_drawing_page = makeReinforcementDrawing(
    structure,
    rebars_list,
    view,
    rebars_stroke_width,
    rebars_color_style,
    rebars_color,
    structure_stroke_width,
    structure_color_style,
    structure_color,
    drawing_left_offset,
    drawing_top_offset,
    drawing_min_right_offset,
    drawing_min_bottom_offset,
    drawing_max_width,
    drawing_max_height,
    template_file,
    dimension_left_offset,
    dimension_right_offset,
    dimension_top_offset,
    dimension_bottom_offset,
)
  • Creates a ReinforcementDrawingView object for given structure and rebar objects list.
  • It returns the reinforcement_drawing_page of type TechDraw::DrawPage.
  • view specifies the view of drawing to be generated. It can be "Front", "Rear", "Left", "Right", "Top" or "Bottom".
  • rebars_stroke_width specifies the stroke-width of rebars in drawing svg.
  • rebars_color_style specifies the color style of rebars. Set it to "Automatic" to automatically select rebars color or "Custom" to choose shape color value from variable rebars_color.
  • rebars_color specifies the fill color for rebars in drawing svg.
   Format: (r, g, b)
   r, g, b value should be between 0 to 1, so you may need to divide value of r, g, b by 255 to get its value between 0 to 1
   Make sure r, g, b must be float
   Example: (0.67, 0.0, 0.0)
  • structure_stroke_width specifies the stroke-width of structure in drawing svg.
  • structure_color_style specifies the fill style of structure. Set it to "Automatic" to automatically select structure color or "Custom" to choose structure color value from variable structure_color.
  • structure_color specifies the fill color for structure in drawing svg. Format: (r, g, b)
  • drawing_left_offset specifies the left offset of drawing view on template_file.
  • drawing_top_offset specifies the top offset of drawing view on template_file.
  • drawing_min_right_offset specifies the minimum right offset of drawing view on template_file.
  • drawing_min_bottom_offset specifies the minimum bottom offset of drawing view on template_file.
  • drawing_max_width specifies the maximum width of drawing on template_file.
  • drawing_max_height specifies the maximum height of drawing on template_file.
  • template_file is the template file to be used for reinforcement drawing page.
  • dimension_left_offset specifies the left offset of dimension from drawing.
  • dimension_right_offset specifies the right offset of dimension from drawing.
  • dimension_top_offset specifies the top offset of dimension from drawing.
  • dimension_bottom_offset specifies the bottom offset of dimension from drawing.

  • It returns structure_drawing_page_dict, a dictionary with structure as key and corresponding reinforcement drawing page as value.
  • structure_list is the list of structural objects to generate their reinforcement drawing. If not provided, structures will be selected from active document acting as Host for rebar objects.
  • rebars_list is the list of rebar objects to be included in drawing. If not provided, rebars objects having Host in structure_list will be selected from active document.
