Arch Rebar Drawing Dimensioning

Description

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

Drawing and dimensioning of reinforcing bars

Usage

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

2. Select Arch Structure object and then click on Reinforcement Drawing Dimensioning.

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

4. Enter all the details related to stroke width and color of rebar and structure.

5. Click on Next button and the dialog box will be updated as shown below.

6. Enter drawing views option, dimensioning and offset details.

7. Click on Next button and the dialog box will be updated as shown below.

8. Enter dimension label and line details.

9. Click on Next button and the dialog box will be updated as shown below.

10. Enter single rebar and multi rebar dimension details.

11. Click on Next button and the dialog box will be updated as shown below.

12. Enter details of dimension and dimension line offsets.

13. Click Finish button to generate drawings.

Reinforcement Drawing

Usage

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

2. In FreeCAD Python console, copy the 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)

Reinforcement Dimensioning

Usage

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

2. In FreeCAD Python console, copy the 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)
