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 two opposite points on the circumference, whose distance defines the diameter of the circle.


This command is accessed from the CAMtastic Editor by choosing the Place » Circle » 2-Points 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 first point on the circumference.
  2. Move the cursor to define the second point on the circumference. As you move the cursor, a line appears to visually define the diameter of the circle, the midpoint of which will be the circle's center. When the diameter is as required, click to define the second circumference point and complete placement of the circle.
  3. Continue placing further circles or right-click, or press Esc, to exit circle placement mode.


  1. Circles will be drawn using the current DCode. Set the required DCode in the DCode field on the CAMtastic panel.
  2. 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.
