A blend feature smooths an edge of a three-dimensional solid part. To create a blend feature, select ShapeBlend from the main menu bar or select one of the blend tools in the Part module toolbox. You create a blend feature in the Part module using the blend tools to do one of the following:
Smooth an edge with a circular blend of a specified radius, as shown in Figure 1140. Select ShapeBlend
Round/Fillet from the main menu bar to create this type of feature.
Bevel an edge with a chamfered blend of a specified length, as shown in Figure 1141. Select ShapeBlend
Chamfer from the main menu bar to create this type of feature.
You can use the blend tools to blend edges of a deformable or discrete rigid part that you created in three-dimensional modeling space. You cannot add a blend feature to a two-dimensional or axisymmetric part; however, you can blend its corners by editing the sketch of the part.
