A Draftsman Bill Of Materials is an automatically generated table object that lists the physical assembly items in a PCB design. The BOM table data is derived directly from the project PCB file, or if one is present in the current project, an Active BOM document. A Draftsman BOM Table can also represent the constituent items from a specified design Variation or a placed Board Assemby View.

The BOM table's visual style and included data content is configurable in (or via) the Properties panel.

A Bill Of Materials table split over two BOM objects. In the above example, the BOM content is filtered to include the items from the Top side Board Assembly View.

To place a BOM table, select the BOM table placement tool . After launching the command, BOM data is retrieved from the source PCB file or Active BOM document, the cursor will change to a cross-hair and the generated BOM table is attached to the cursor. Move the cursor to the desired position then click to confirm the placement.

Note that BOM data is retrieved from the PCB document specified in the Source section of the Properties panel when in Document Options mode. To change the panel to that mode, deselect all objects in the design space (click in free space).

The position of a placed Bill Of Materials may be graphically changed by selecting the table in the design space then dragging it to a new location. Note that the table cannot be graphically resized, but will automatically scale to accommodate the font style/size as specified in the Properties panel.

The data included in a Draftsman BOM table is determined by settings in the Properties panel and the potential presence of an ActiveBOM document in the project:

When an ActiveBOM document is available in the current project, its configuration and content becomes the data source for a Draftsman BOM Table. Note that this applies when the Data Source entry in the Properties panel is set to Project – an available ActiveBOM document is not used as a source when the Data Source property is set to Board.
When an ActiveBOM document is not included in the project (or the Data Source option is set to Board), the data in a Draftsman BOM Table is drawn directly from the source project files. An Alias entry for a table column entry Name (available in under the Properties panel’s Columns tab) is then editable since it is not determined by an Alias property entry in an ActiveBOM document.

In general, the Properties panel options can restrict BOM entries to those included in the Board layout (as opposed to the entire PCB project, including any custom component Parameters) or to a specific Variation of the design. Further tailoring of the included entries is available through specifying the top or bottom view of a placed Board Assembly View.

Use the Properties panel's Columns tab to manage the BOM table's data columns. This allows control of the BOM table column visibility, text alignment, width, and data sort order. BOM Table headings may be changed by entering an Alias for a table column parameter name – applies if an ActiveBOM document is not determining the table content (see above).

Manipulate the columns of a placed BOM Table in the Columns tab of the Properties panel.

Split BOM tables

The Bill of Materials (BOM) document for most advanced PCB projects tends to have a large number of entries, which can be difficult to recreate as a table that will fit into a drawing document. Rather than resorting to font and table scaling, multiple custom table entries or an external document, the Split BOM capability in the Properties panel allows a BOM Table to be presented over a number of 'pages'.

To create the multiple BOM Pages, select a placed BOM (which is likely to exceed the document Sheet height) and check the Limit Page Height box in the Properties panel’s Pages section. This will restrict the height of the BOM table to the nominated height entry (Max Page Height, mm), and therefore the number of lines shown in the BOM table.

Hover mouse cursor over image to see the Limit Page Height result.

Draftsman detects that the entire BOM is not shown, as indicated by the panel's Page entry (for example, 1 from 2), and the associated drop-down menu allows you to nominate which Page is shown. To add further Pages of the BOM (here, BOM Table ID: 0), place another BOM (Place » Bill of Materials) and specify the next page under Page in the Pages section of the Properties panel.

Since each Page of the BOM is placed by adding another BOM table, and then configuring it accordingly, the individual BOM Pages (sections) can be placed on any Sheet in a Draftsman document. To place another, different set of split BOM Pages, specify an alternative BOM Table ID on a placed BOM – say, 1 rather than 0.

Note that the Max Page Height property specifies the height of the first page in the BOM Table. When the second page is selected (Page 2), the Max Page Height property is defining the height of the first excluded page (Page 1). Page 2 therefore shows the remaining BOM entries. Start by making the Max Page Height property identical for each page.

Bill Of Materials Properties

The Bill Of Materials mode of the Properties panel.

General Tab

Title

Title – the title name string that will be displayed (if enabled) with the Bill Of Materials table. Use the associated button to toggle its visibility. Enter the title name and any desired system/custom parameters to create a meaningful name for the placed view. See the Parameters section in the panel's Document Options mode for a list of the currently available parameters.
Location – select the drop-down to choose from a range of relative locations for the title. The Manual option is automatically selected if the title is manually moved (dragged and dropped to a new location).
Font – sets the displayed font used for the table's title string.
- Use Document Font checkbox selected – the title font used is that defined by the document options. See the Document Font entry in General section of the Properties panel when in Document Options mode.
- Use Document Font not selected – use the drop-down menus to choose the desired font type and size, and select the lower buttons to enable text attributes. The associated color button () opens the color selector where the font color can be specified by RGB or HEX value, by freeform selection, or from a range of presets. Note that the slider control sets the color Opacity level, where 0% represents full transparency.

Properties

Table Line Style – the thickness, color and pattern style of the lines used to render the BOM table. Use the line weight drop-down menu to choose from a range of line thickness presets and the line pattern menu to choose from a range of line styles. The associated color button () opens the line color selector, as outlined for the Font property above.
Justification - select the desired justification by clicking on an arrow that corresponds with the desired justification or the circle to center.
Even Row Color – select the contrasting color for even rows in the BOM table.
Non-Even Row Color – select the contrasting color for odd rows in the BOM table.
Font – sets the font used for the table data content.
- Use Document Font checkbox selected – the font used is that defined by the document options. See the Document Font entry in General section of the Properties panel when in Document Options mode.
- Use Document Font not selected – use the drop-down menus to choose the desired font type and size and select the lower buttons enable text attributes. The associated color button () opens the color selector, as outlined above.
- Table Header Bottom – check to position the column header row at the bottom of the table and reverse item listing order.
Data Source
- Project – all BOM related data from the PCB project files are used to populate the Draftsman BOM Table, e.g., PCB project components that do not have a symbol or footprint are included.
  When the Data Source is set to Project, the BOM Table will be populated by data from an ActiveBOM document in the PCB Project, if one is available. Use Draftsman's Tools » Update Board command to pick up live changes in an ActiveBOM document.
  See BOM Management with ActiveBOM for more information on creating and configuring an ActiveBOM document.
- Board – entries in the Draftsman BOM Table are constrained to component items that are present on the physical project PCB.
Assembly View – use the drop-down menu options to filter the listed BOM entries to the items shown in a specified Board Assembly View. The options include any placed Assembly Views, or simply All items in the PCB design.
View Mode
- Base – a table row is assigned to each unique component type and lists all included items in the Designator column. If a Variant has been selected, only its items will be listed.
- Flat – a table row is assigned to each component item. If a Variant has been selected, only its items will be listed.
- Consolidated – if the source project includes Variants, the BOM Table will include component entries from all design variations. Selecting this option will automatically set the Variant option to All.
Variant – use the drop-down menu to select a PCB design variation, if available, as a data source for the BOM table. The Document:xx option is a Variant specified for the document under Document Options in the Properties panel (Source section). The placed BOM table will appropriately reflect assembly items that are not included or have varied parameters.
Show Components – when a variant is selected, use the drop-down to select which component entries to be included in the list:
- Fitted – show only components that are Fitted for the currently selected design variant.
- All – show all components for the currently selected design variant.
- Not Fitted – show only components that are Not Fitted for the currently selected design variant.
- Replaced – show only components for which alternate parts have been selected or fitted components with varied parameter values in the currently selected design variant.
A BOM table with the Fitted, Not Fitted or Replaced options selected for Show Components works with Base and Flat options selected for View Mode (not Consolidated).

Columns Tab

Columns

A tabular list of the columns and data shown in the BOM table. The entries may be edited to specify the BOM table's included (visible) columns and their text alignment (Align - Properties panel only), width (Width) and displayed list sort order/priority (Order). Enter an alternative name for a BOM Table header in its corresponding Alias entry – note that this entry cannot be edited if an ActiveBOM document is determining the BOM Table data (see Properties – Data Source, above).

Column Type filter checkboxes (Properties panel only) – check the Schematic (), PCB (), Server () and BOM () options to populate the available columns list with matching parameter data types. Deselect all types to list only those columns that are visible () in the BOM Table. See ActiveBOM for more information about parameter data sources.
Move Left / Right buttons – click to move the selected entry up or down by one count, and therefore, to the left or right in the BOM table column order. Available for columns set to visible.
Default button – click to restore the table columns to the default entries (as defined by the BOM table object Preferences).
