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

Applied Parameters: None


This command is used to place offset lines/arcs on the current document. An offset is a 'shadow' of the selected line or arc, drawn at a specified distance from the original.


This command can be accessed from the CAMtastic Editor by:

  • Choosing the Edit » Objects » Offset command from the main menus.
  • Clicking the  button, on the Editing Tools drop-down () of the Utilities toolbar.


After launching the command, the Enter Value dialog will appear. Use this dialog to specify a value for the offset distance. After clicking OK, the cursor will change to a square and you will be prompted to select a single line or arc object. Simply position the cursor over the required object and click. You will then be prompted to select the side to offset. Position the cursor to one side of the line or arc and click - the offset line/arc will be drawn at the specified offset distance from the original.

Continue selecting further lines/arcs to offset (using the same distance), or right-click, or press Esc, to exit.


  1. The offset distance will use the current units for the workspace - either inches or millimeters. Units can be changed either from the CAMtastic panel, or the CAM Editor - Drawing Modes page of the Preferences dialog.
