Applied Parameters: CommandMode=CAM

Summary

This command is used to place polygon void objects on the current document. A polygon void is a polygon that contains no flashes or draws and requires an outline to be made of straight lines.

Access

This command is accessed from the CAMtastic Editor by choosing the Place » Polygon Void command from the main menus.

Use

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

  1. Position the cursor at the required location in the workspace and click to anchor the start point for the polygon.
  2. Move the cursor and click again to place the next vertex point in the polygon boundary.
  3. Continue placing further vertices, clicking each time, until the desired shape for the polygon void has been achieved.
  4. Right-click to complete placement. There is no need to "close" the polygon as the software will automatically complete the shape by adding a line from the start point to the final point placed. All flashes and draws that fall inside the boundary of the polygon will be cleared.
  5. Continue placing further polygon voids, or press Esc to exit polygon placement mode.

Tips

  1. A polygon void must have at least three distinct vertices.
  2. A Polygon void behaves exactly the same as a polygon, but when placed, all contents within its boundary are cleared. You can put polygon voids inside a polygon.
  3. Polygon voids will be drawn using the current DCode. Set the required DCode in the DCode field on the CAMtastic panel.
  4. Polygon voids 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.
