| Create sheet on failure | 
                                             If this option is active and the blends cannot be performed on a selected edge, a sheet entity is created.

| Local validate | This option works together with the Repair option. It verifies whether the region in which the blend is to be created is still valid. If it is not valid, it blocks the blend creation which is the case for the selected edge   with the radius specified in   in the following illustration. |

                                             This option works together with the Local validate option. If it is active and the Local validate option invalidated the blend creation, it tries to automatically fix the issue and, if successful, creates the blend as shown in   |

                                             This option can be used when a blend completely overlaps a feature.

                                        This option allows you to define the blending order. If this option is active, the convex edges are blended first.
