Description

The Bill Of Material tool allows the user to create bill of material of reinforcing bars.

This command is part of the Reinforcement Addon, that you can install with the Addon Manager via the menu Tools → Addon manager → Reinforcement.

Bill Of Material of reinforcing bars

Usage

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

2. Then select Bill Of Material from the rebar tools.

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

Dialog Box for the Arch Rebar BOM tool

4. Modify data to suit your requirements.

5. To edit Bill Of Material SVG configurations, click on Edit SVG Configurations. A dialog box will pop-out as shown below.

6. Modify Bill Of Material SVG configurations and then click on OK to apply changes.

7. Click OK or Apply to generate Bill Of Material for rebars.

8. Click Cancel to exit the dialog box.

Properties

General:

  • DataColumn Headers: A dictionary with column_data as key and tuple (column_display_header, column_sequence) as value.
  • DataColumn Units: A dictionary with keys: "Diameter", "RebarLength", "RebarsTotalLength" and their corresponding units as value.
  • DataDiameter Weight Map: A dictionary with diameter as key and corresponding weight as value.
  • DataRebar Length Type: Rebar Length Type specifies the type of rebar length used for BOM calculations i.e. "RealLength" or "LengthWithSharpEdges".
  • DataRebar Objects: A list of ArchRebar and/or rebar2 and/or structures (to select ArchRebar in that structure) objects.

SVG:

  • DataFont Family: Font Family of text in BOM SVG.
  • DataFont Filename: Font filename corresponding to font family required in console mode.
  • DataFont Size: Font size in mm.
  • DataColumn Width: Width of each column in BOM SVG table.
  • DataRow Height: Height of each row in BOM SVG table.
  • DataLeft Offset: Left offset of BOM SVG table.
  • DataTop Offset: Top offset of BOM SVG table.
  • DataMinimum Right Offset: Minimum right offset of BOM SVG table.
  • DataMinimum Bottom Offset: Minimum bottom offset of BOM SVG table.
  • DataMaximum Width: Maximum width of BOM SVG table.
  • DataMaximum Height: Maximum height of BOM SVG table.
  • DataTemplate File: Template svg file for BOM SVG.
  • DataOutput File: BOM SVG Output file.

Scripting

See also: Arch API, Reinforcement API and FreeCAD Scripting Basics.

The Bill Of Material tool can be used in macros and from the Python console by using the following function:

Create Bill Of Material Spreadsheet

bom_spreadhseet = makeBillOfMaterial(
    column_headers=None,
    column_units=None,
    dia_weight_map=None,
    rebar_length_type=None,
    rebar_objects=None,
    obj_name="RebarBillOfMaterial",
)
  • Creates a RebarBillOfMaterial spreadsheet object for given rebar_objects.
    • If rebar_objects list is empty, then RebarBillOfMaterial spreadsheet will be created all rebars in a model.
  • column_headers is a dictionary with keys: "Mark", "RebarsCount", "Diameter", "RebarLength", "RebarsTotalLength" and values are tuple of column_header and their sequence number.
   Example: {
                "Mark": ("Mark", 1),
                "RebarsCount": ("No. of Rebars", 2),
                "Diameter": ("Diameter in mm", 3),
                "RebarLength": ("Length in m/piece", 4),
                "RebarsTotalLength": ("Total Length in m", 5),
            }
            set column sequence number to 0 to hide column.
  • column_units is a dictionary with keys: "Diameter", "RebarLength", "RebarsTotalLength" and their corresponding units as value.
   Example: {
                "Diameter": "mm",
                "RebarLength": "m",
                "RebarsTotalLength": "m",
            }
  • dia_weight_map is a dictionary with diameter as key and corresponding weight as value.
   Syntax: {
                6: FreeCAD.Units.Quantity("0.222 kg/m"),
                8: FreeCAD.Units.Quantity("0.395 kg/m"),
                10: FreeCAD.Units.Quantity("0.617 kg/m"),
                12: FreeCAD.Units.Quantity("0.888 kg/m"),
                ...,
            }
  • rebar_length_type specifies the type of rebar length used for BOM calculations; it can be "RealLength" or "LengthWithSharpEdges".
  • rebar_objects is a list of ArchRebar and/or rebar2 and/or structures (to select ArchRebar in that structure) objects.
