To Add a Sketched Tool
You can use sketched tools for Trajectory Milling or Trajectory Turning NC sequences.
1. On the Tool Setup dialog box menu bar, click Edit > Sketch.
2. The system increments the pocket Number by 1 with respect to the last one currently in the Tool Table and generates a default Name for the tool. The Offset field is left blank.
3. Modify Name as desired.
4. Click Sketcher.
5. The system starts the Sketcher user interface and opens a new window. Sketch the tool section.
* 
To correctly simulate the sketched tools on the Material Removal tab, create the sketcher entities from the lower-most point upward in the counter-clockwise direction.
