You can insert a table-based
Bill of Materials or an Excel-based
Bill of Materials in a drawing, but not both.When you create a bill of materials in a drawing of a route assembly, you can select a template that causes each unique cut length of pipe to be listed as a separate item. The template also assigns part numbers based on a configuration-specific property.
Otherwise, inserting and editing a BOM is the same as it is with other types of assembly drawings.
You can insert a table-based
Bill of Materials or an Excel-based
Bill of Materials in a drawing, but not both.
To create a table-based bill of materials for a route assembly:
Select
a drawing view that contains a route assembly, and click Bill
of Materials 
(Table toolbar) or Insert,
Tables, Bill
of Materials.
In the
Bill of Materials
PropertyManager, select a template under Table
Template (bom-standard.sldbomtbt,
for example), set other options as needed (Indented
assemblies under BOM Type,
for example), and click 
.
If you did not select Attach to anchor, click in the graphics area to place the table.
To add a column to the bill of materials:
Right-click in a column of the table and select Insert, Column Left or Column Right.
In the Column PropertyManager:
Select Custom Property under Column Properties.
Select a custom property from the list (SWPipeLength, for example).
Edit the column header under Title (PIPE LENGTH, for example).
Click
.
The column is populated with values of the selected custom property.
To create an Excel-based BOM for a route assembly:
Select a drawing view that contains a route assembly,
and click Excel Based Bill of Materials
(Table toolbar) or Insert,
Tables, Excel Based Bill of Materials.
In the Select BOM Template dialog box, browse to <install_dir>\lang\<language>, and select Piping BOM Template.xls.
Select options in the Bill of Materials Properties dialog box, then click OK.
The BOM includes special columns for piping assemblies:
The PART NO. column displays the configuration-specific property SWbompartno (the sample routing parts include this property in the design tables).
Each configuration of a fitting has a different part number.
All route segments cut from the same raw stock have the same part number.
Each unique cut length of pipe is listed as a separate item using the property SWPipeLength, with the length displayed in the CUT LENGTH column.
If you edit the template
in Excel, do not
edit the text in the Name box
for any of the default columns.
You can create custom columns in the Piping BOM Template. For example, you can create a column for the property SWElbowAngle (the angle of an elbow component).
See Bill of Materials - Custom Properties for more information.
Note also that there are hidden columns in the template; do not show, edit, or delete the hidden columns.
