Example: Creating a Rib Top Feature
 
* In this example, we are going to create Pocket features on both sides of the rib prior to creating the Rib Top feature. This is not necessary. You can create the Rib Top feature first (for example, if you want to machine it before machining the Pockets); the geometry of the Rib Top feature is going to be exactly the same. When you select the top of the rib, the system extends it vertically up regardless of whether there is stock material to the sides of the rib or not.
To generate the proper features for machining this model, start by defining two Pocket features on both sides of the rib:
1. Create a Pocket feature and select the bottom of the cavity (1) on one side of the rib as the Floor surface. The system creates the Pocket feature, as shown in the following illustration.
2. Create another Pocket feature and select the bottom of the cavity (2) on the other side of the rib as the Floor surface. The system creates the second Pocket feature.
3. Create a Rib Top feature and select the top of the rib (3) as the Floor surface.
The system creates a Rib Top feature as shown in the next illustration. The Hard Walls are highlighted in red; the Soft Walls are highlighted in cyan.
