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:

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.
