Applied Parameters: None


This command is used to fill selected closed boundary objects with optimized line strokes.


This command can be accessed from the CAMtastic Editor by:

  • Choosing the Analysis » Fill Boundaries command from the main menus.
  • Clicking the  button, on the Fabrication Tools drop-down () of the Utilities toolbar.


After launching the command, the cursor will change to a small square and you will be prompted to select closed boundary objects that you wish to fill. Simply position the cursor over part of the boundary for an object, and click. Continue adding objects to the selection and then right-click when done.

The Fill Boundaries dialog appears. Use this dialog to set up the options for the fill, including selection of layer for the fills to reside on, the minimum tool size to be used, and whether to limit the filling process to the use of one tool, or multiple tools.

After defining the options in the dialog as required, click OK to proceed. All selected boundaries will be offset inward until no further offset is possible (or one-time only if the Use Single Internal Offset option is enabled). The boundaries will then be filled with a line pattern, in accordance with the options defined.


  1. A boundary must be properly closed in order to use this command. If a boundary has been created using line segments, you will need to use the Join command to make a proper closed boundary.
