Part Families are split into two tabs, Connection Part Families and Junction Part Families. Each tab allows part families for that section to be added, deleted, renamed, or merged. Part Family names must be unique and are case sensitive - if duplicate names are entered these are modified to be unique.
Part Families added will be available for selection in Connections and Junctions. The part family selected for each object will be used in InfoDrainage for Civil3D to group objects during part mapping.
If Connections or Junctions are created or loaded from another source, any part families that are not available are added automatically.
Toolbar
