Parent page: Multi-board Schematic Objects

A placed ModuleA placed Module


A Module is a rectangular object that can be placed on a multi-board Design document to represent a child PCB project design. The connectivity between PCB projects that make up a multi-board system design is established by placing modules on the schematic and connecting their exposed connectors (Module Entries) together using virtual connections, such as Wires.


Modules are available for placement in the multi-board schematic editor as follows:

  • Choose the Place » Module command from the main menus.
  • Click the  button on the Active Bar located at the top of the design space.
  • Right-click in the drawing design space then select Place » Module from the context menu.


After launching the command, the cursor will change to a cross-hair and the editor will enter Module placement mode. Placement is made by performing the following sequence of actions:

  1. Click to anchor the first corner of the Module shape.
  2. Move the cursor to adjust the size of the Module rectangle and click again to complete placement.
  3. Continue placing further Modules or right-click or press Esc to exit the placement mode.
The default settings for the Module object are available in the Multi-board Schematic - Defaults page of the Preferences dialog.

Graphical Editing

This method of editing allows a placed Module object to be selected in the design space and graphically edit its size, shape or location.

Select a Module by clicking on its fill or outline. Once selected, editing handles/nodes are available at each corner vertex.

  • Click and drag a node to reposition it and alter the size of the Module rectangle.
  • Click and drag the Module object to reposition it in the schematic.

Non-Graphical Editing

Properties page: Module Properties

The non-graphical method of editing a Module is available in the multi-board Properties panel, which provides editable property fields for the item that is currently selected in the design space.

To open the Properties panel and access the properties of a placed Module:

  • After selecting the Module object, select the Properties panel from the Panels button at the bottom right of the design space or select View » Panels » Properties from the main menus.
  • Double-click on the Module object.
  • Right-click on the Module then select Item Properties from the context menu.

If the Properties panel is already active, click on the Module to access its properties in the panel.

The Module properties can be accessed prior to entering placement mode, from the Multi-board Schematic – Defaults page of the Preferences dialog. This allows the default properties for the Module object to be changed, which will be applied when placing subsequent Modules.

Editing Multiple Objects

The Properties panel supports multiple object editing where the property settings that are identical in all currently selected objects may be modified. When multiples of the same object type are selected, a Properties panel field entry can be edited for all selected objects. If values of a property are different for objects in the selection, the appropriate field will be shown as an asterisk (*); a new property value will be applied to all selected objects.

Right-click Commands

A range of commands are available for quick access in the Design sub-menu when right-clicking on a Module. Note that some commands in the context menu can be accessed when a Module is not selected. 

  • RunERC – perform an Electrical Rules Check (ERC) on the Multi-board project design and its sources.
  • Import From Child Projects – propagate the design data from all source (child) PCB projects into their specified Modules.
  • Import From Selected Child Projects – propagate the design data from the corresponding source (child) PCB projects for the currently selected Module(s).
  • Update Child Projects – perform an Engineering Change Order (ECO) to edit the source projects to match (synchronize to) any related changes in the Multi-board document. For example, a change to the pinout configuration of a system interconnection header/plug part.
  • Update Selected Child Projects – perform an ECO to edit the source project to match any related changes in the currently selected Module.
  • Update Assembly Projects – perform an ECO to edit the Multi-board PCB Assembly document to match any related changes in the Multi-board Schematic document.
  • Crossprobe to PCB/Multi-board – cross probe to (open and zoom to) the selected Module’s corresponding the board layout design.
  • Crossprobe to Schematic – cross probe to the selected Module’s corresponding schematic document sheet.
  • Crossprobe to MBA board – cross probe to the selected Module’s corresponding board layout in the Multi-board Assembly document.
  • Connection Manager – open the multi-board editor’s Connection Manager dialog.
