◦ Feature Name—The default feature name, such as Undercut1 (the system increments the number for the next Undercut feature). You can type a customized name.

◦ Define Feature Ceiling—Select the Ceiling surface for the feature, that is, the top surface of the undercut (similar to defining the Floor surface for other feature types).

◦ Adjust Feature Boundaries—Change the shape of the feature walls using Sketcher.

◦ Define Program Zero—Change the coordinate system used for feature definition and machining.

◦ Adjust Soft Walls—Change Hard Walls to Soft and Soft Walls to Hard.

◦ Adjust Feature Bottom—Adjust the Floor depth of feature (by default, an Undercut extends down until the system finds a horizontal surface of the reference part; if such a surface is not found, the Undercut extends all the way through the stock). To specify a different Floor depth, select a surface, a datum plane, or type a value along the z-axis of the feature-level Program Zero coordinate system.
