Example: Creating a Flange Feature
In the NC Model shown in the illustration below, the stock is a casting with a large cavity in the middle of the top surface. To machine the top of the reference model and avoid air machining, create a Flange feature. Select the top face of the reference model (1) as the Floor surface.
The system creates a Flange feature as shown in the next illustration. The outer boundaries of the stock are Soft Walls; they are highlighted in cyan.
