To add machining to a part, you must first select the desired tool, then enter a depth and specify if the operation will be on FACE 5 or FACE 6. For routing and sawing tools, you will need to select the type of tool compensation to use: Left, Center, or Right.

To use the Pick Existing Entities, you must have an object or polyline drawn.

1. For vertical drilling operations, the diameter of the circle drawn has to match the diameter of the tool used.
   
2. For horizontal drilling operations, you will need to either draw a rectangle and convert it to a polyline or draw a polyline – the width of the rectangle must match the diameter of the tool being used, and the length must match the depth you specified.
   
3. Also, for horizontal drilling operations, a value in the Other Z Value will move the center of the drilling operation along with the thickness of the part.
   

When using the Draw function, you must do the following:

1. For vertical and horizontal drilling operations, you must pick a point in the drawing based on the center of the hole. As an option, you can select a second point (creating a straight path) and specify the distance between holes.
   
2. For routing operations, select the type of machining operation to draw from the list:
   
1. None - Allows you to draw a polyline freely. Once the command has been completed, the machining will be applied to the new polyline.
   
2. Square Cutout/Pocket - Allows you to create a rectangular cutout. Requires you to pick a point for the starting corner of the rectangle and then to pick the opposite corner creating the width and length of the rectangle simultaneously.
   
3. Round Cutout/Pocket - Allows you to create a circular cutout. It requires you to pick a point for the center of the circle and specify the diameter of the hole.
   
4. Corner Notch - Allows you to notch the corner of a part (for example, a toe kick notch). It requires you to pick a corner on the part and then specify the width and length of the notch.
   
5. Radiused Corner Notch - Allows you to draw a concave radius on a corner. Requires you to pick a corner on the part and then specify the radius.
   
6. Chamfer Corner - Allows you to create a diagonal cut across the corner of a part. It requires you to pick a corner on the part and then specify the distance along each edge.
   
7. Fillet Corner - Allows you to round over the corner of a part. Requires you to pick a corner on the part and then specify the radius.
   
3. For sawing operations, you must create straight, vertical, or horizontal lines by pick a start and endpoint.
