Arch Rebar BOM

Description

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

Bill Of Material of reinforcing bars

Usage

1. Select Arch Rebar objects you want to include in the 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 the model.

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

3. A dialog box will pop-out on the 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.

Dialog Box for the Arch Rebar BOM SVG configuration editing

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.

Scripting

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_spreadsheet = 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 for all rebars in a model.
column_headersis a dictionary with keys: "Host", "Mark", "RebarsCount", "Diameter", "RebarLength", "RebarsTotalLength" and values are tuple of column_header and their sequence number.

Example: { "Host": ("Member", 1), "Mark": ("Mark", 2), "RebarsCount": ("No. of Rebars", 3), "Diameter": ("Diameter in mm", 4), "RebarLength": ("Length in m/piece", 5), "RebarsTotalLength": ("Total Length in m", 6), } set column sequence number to 0 to hide column.

column_unitsis a dictionary with keys: "Diameter", "RebarLength", "RebarsTotalLength" and their corresponding units as value.

Example: { "Diameter": "mm", "RebarLength": "m", "RebarsTotalLength": "m", }

dia_weight_mapis a dictionary with diameter as key and corresponding weight as value.

rebar_length_typespecifies the type of rebar length used for BOM calculations; it can be "RealLength" or "LengthWithSharpEdges".
rebar_objectsis a list of ArchRebar and/or rebar2 and/or structures (to select ArchRebar in that structure) objects.

column_widthspecifies the width of each column in the bill of material table SVG.
row_heightspecifies the height of each row in the bill of material table SVG.
bom_left_offsetspecifies the left offset of the bill of material SVG on template_file.
bom_top_offsetspecifies the top offset of the bill of material SVG on template_file.

bom_table_svg_max_heightspecifies the maximum height of the bill of material table in SVG.
template_filespecifies the template file used to place the generated bill of material table on it. It must be a valid TechDraw template file as here.
output_filespecifies the output file to write generated bill of material SVG.
rebar_objectsis a list of ArchRebar and/or rebar2 and/or structures (to select ArchRebar in that structure) objects.
reinforcement_group_byspecifies how reinforcement objects should be grouped; it can be "Mark" or "Host".
return_svg_onlyspecifies if the BOMContent object is to be created or not. If return_svg_only is True, then neither BOMContent object is created nor SVG is written to output_file. And it returns the SVG element.
