To Create a Top Round Feature
A Top Round feature can consist of a single rounded edge, a single chain of rounded edges (open on both ends), or a single closed loop of rounded edges (for example, on top of a Pocket feature).
1. On the Machining tab, click the arrow next to Top Chamfer and select Top Round.
The TOP ROUND dialog box opens with the following elements:
Feature Name—The default feature name, such as TopRound1 (the system increments the number for the next Top Round feature). You can type a customized name.
Define Feature Floor—Select the Floor surface for the feature (the surface of the round).
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.
2. Select the Floor surface(s). If the Top Round consists of a chain or a loop of rounded edges, select all the rounded surfaces and click Done Sel. On the SELECT SRFS menu, click Done/Return.
3. Use the other elements, if needed. Click next to the element to display the current setting. The Preview button lets you check the feature geometry by highlighting the Hard Walls in red, Soft Walls in cyan.
4. Click OK to complete the feature, Cancel to quit.
