The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to toggle between the use of Imperial and Metric measurement units, for the active Multi-board Schematic document (*.MbsDoc).

For a high-level look at multi-board design within Altium Designer, see Designing Systems with Multiple Boards.


This command can be accessed from the Multi-board Schematic Editor by:

  • Choosing the View » Toggle Units command, from the main menus.
  • Using the Q keyboard shortcut.


After launching the command, the units of measurement in force for the active Multi-board Schematic document will be toggled. If they were previously Imperial units (mil), they will toggle to Metric (mm), and vice-versa.


  1. This command effectively toggles the setting for the Units field, in the General section of the Properties panel, when accessed with no design objects currently selected in the main workspace.
  2. You can quickly verify the active units from the Status Bar, by looking at the entry for the coordinates, at the left-hand end of the bar.
