Description

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

This command is part of the Reinforcement Addon, an external workbench that can be installed with the 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 and dimensioning from different views for each Arch Structure element.

from ReinforcementDrawing.make_reinforcement_drawing import (
    makeStructuresReinforcementDrawing,
)

for view in ("Front", "Rear", "Left", "Right", "Top", "Bottom"):
    struct_drawing_page_dict = makeStructuresReinforcementDrawing(
        view=view, perform_dimensioning=True
    )
    for drawing_page in struct_drawing_page_dict.values():
        drawing_view = drawing_page.Views[0]
        drawing_view.setExpression(
            "LeftOffset",
            u".Template.Width.Value / 2 - .Width.Value * .Scale / 2",
        )
        drawing_view.setExpression(
            "TopOffset",
            u".Template.Height.Value / 2 - .Height.Value * .Scale / 2",
        )
        drawing_view.recompute(True)
        drawing_page.recompute(True)

Scripting

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

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.
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)

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.
dimension_left_offset_increment is the increment in left offset to move each new dimension label away from drawing.

dimension_top_offset_increment is the increment in top offset to move each new dimension label away from drawing.
dimension_bottom_offset_increment is the increment in bottom offset to move each new dimension label away from drawing.
dimension_single_rebar_outer_dim specifies if dimension lines are to be outside of reinforcement drawing, in case of single rebar is visible.
dimension_multi_rebar_outer_dim specifies if dimension lines are to be outside of reinforcement drawing, in case of multiple rebars are visible.
