Parent page: CAMtastic Commands

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

Applied Parameters: CommandMode=CAM


This command is used to place circle objects onto the current document. The circle is drawn using a center point and a numerically defined radius.


This command is accessed from the CAMtastic Editor by choosing the Place » Circle » Center, Radius command from the main menus.


After launching the command, you will enter circle placement mode. Placement is made by performing the following sequence of actions:

  1. Position the cursor at the required position and click to define the center point for the circle.
  2. The Enter Value dialog will appear, prompting you to enter a value for the radius. After specifying the radius required, click OK to complete placement of the circle.
  3. Continue placing further circles or right-click, or press Esc, to exit circle placement mode.


  1. The radius entered will use the current units for the workspace - either inches or millimeters. Units can be changed either from the CAMtastic panel, or from the CAM Editor - Drawing Modes page of the Preferences dialog.
  2. Circles will be drawn using the current DCode. Set the required DCode in the DCode field on the CAMtastic panel.
  3. Circles will be drawn on the current layer. The current layer is displayed on the CAMtastic panel at the top of the layers list. Double-clicking on any layer in the layers list will cause it to become the current layer.
