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

Applied Parameters: None


This command is used to delete objects from the current document. The command functions in two modes, catering for whether or not object(s) are currently selected in the workspace.


This command can be accessed from the Schematic Editor and the Schematic Library Editor by choosing the Edit » Delete command from the main menus.


After launching the command, what happens next depends on whether object(s) are currently selected in the workspace:

  • Object(s) currently selected - the selection will be removed from the document.
  • No object(s) currently selected - the cursor changes to a crosshair and you will enter object deletion mode. Position the cursor over an object then click or press Enter to delete it. Continue deleting further objects or right-click or press Esc to exit object deletion mode.


  1. All deletions can be restored by using the Undo command.
  2. If an object is locked and you try to delete it, you will be prompted with a confirmation dialog alerting you to this and asking if you want to continue.
