Chapter 7: Selecting Features

Building a setback fillet

The setback fillet is the most complex of the fillet options. You can use the Setback option in con-

junction with constant radius, multiple radius, and variable radius fillet types. A setback fillet

blends several fillets together at a single vertex, starting the blend at some “setback” distance along

each filleted edge from the vertex. At least three, and often more, edges come together at the set-

back vertex. Figure 7.52 shows the PropertyManager interface and what a finished setback fillet

looks like. The following steps demonstrate how to use the setback fillet.

to these vertices will be filleted

Setting up a setback fillet can take some time, especially if you are just learning about this feature.

You must specify values for fillet radiuses, select edges and vertices, and specify six setback dis-

tances. If you are using multiple radius fillets or variable radius fillets, then this becomes an even

larger task. The steps are as follows:

1. Determine the type of fillet to be used:

l (^) Constant radius fillet
l Multiple radius fillet
l (^) Variable radius fillet

2. Select the edges to be filleted. Selected edges must all touch one of the setback vertices
   that will be selected in a later step.


3. Assign radius values for the filleted items. Figure 7.53 shows a sample part that illus-
   trates this step.
