Now reading version 15.1. For the latest, read: Off-Grid Object for version 21
Applies to Altium Designer versions: 15.1, 16.0, 16.1, 17.0 and 17.1

Parent category: Violations Associated with Others

Default report mode:


This violation occurs when an object is not aligned to the current Snap grid.


If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog) an offending object will display a colored squiggle beneath it. A notification is also displayed in the Messages panel in the following format:

Off grid <ObjectIdentifier> at <Location>


  • ObjectIdentifier identifies the specific object that is currently off-grid. The identifier is composed of the object's type and its name/designator (e.g. Pin <PinDesignator>).
  • Location is the X,Y coordinates for the object's electrical hotspot.

Recommendation for Resolution

Ensure that the Snap grid is enabled on the Sheet Options tab of the Document Options dialog (Design » Document Options). The offending object can be moved back onto grid manually, or by using the Edit » Align » Align To Grid command.
