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

Applied Parameters: CommandMode=NC


This command is used to place rout circles on the current document. The inside circle will be routed in a counter-clockwise direction.


This command is accessed from the CAMtastic Editor by choosing the Place » Drill » Circle C-Clockwise (G33) command from the main menus.


First, ensure that the layer you wish to place a rout circle on, is the active layer. This is achieved by double-clicking on the layer name, in the layers list area of the CAMtastic panel.

After launching the command, the Select Mill/Drill Tool dialog will appear. Choose the tool you wish to use for routing the circle from the list of available tools. After clicking OK, the Enter Value dialog will appear. Use this dialog to enter a value for the diameter of the outside circle, in the currently selected workspace units (inches or mm).

After clicking OK, you will be returned to the main design window and prompted to select the position for the center of the circle. Simply move the cursor to the required position and click to effect placement of the rout circle.

Continue placing further rout circles, or right-click, or press Esc, to exit.


  1. In order for this command to be available, make sure that you are in the NC Editor, rather than the CAM Editor. Editor selection is carried out from the View menu.
  2. In order to add rout circles, tools must already have been defined, otherwise you will get a dialog alerting you to this fact, and you will be directed to the Tool Table dialog (Tables » NC Tools), from where you can add tool definitions.
  3. The fastest way to generate tools is to generate NC Drill files from the PCB design document. These are imported into the CAMtastic Editor, and the tool definitions added to the Tool Table dialog.
