To engrave pockets that are wider than the chamfer tool's diameter, follow these steps:

  * In this example, the engraving should be 3mm deep
  * **OP 1**: 2D pocket. 
    * Set bottom height to the selected contour with an offset of -3mm.
    * under radial stock to leave, enter the radius of the V-bit at 3mm from the tip
      * to calculate this offset, make a cross-sectional drawing of the V-bit and measure the diameter at the correct distance (3mm) from the tip. Divide this length to become the radius.

  * **OP 2**: Engraving operation with V-bit
    * Set bottom height to the selected contour with an offset of -3mm.
