About Group with Equal Radius Points
You can group together point sets that have the same fillet radius value into a logical group. To create the group, you mark each point set as a group member by selecting the Group with equal radius points check box on the Placement tab.
When you select a point set that is part of a group, the other group members are highlighted in the point set list with a half tone of color.
To add a point set to a group, select the point set, and select the Group with equal radius points check box.
To remove a point set from a group, select the point set, and clear the Group with equal radius points check box.
To change the fillet radius value for an entire group, select a group member and edit the fillet radius. The change is applied to the selected point set and to all other group members.
