The Instance Edit Command

Allows you to edit information about a specific family instance in your project.

If nothing is selected, you will be prompted to select a family instance to edit.

If a piece of electrical equipment is selected, the Panel Edit dialog box will open with the selected electrical equipment active.

If a family instance is selected, or after you select a family instance, one of the Instance Edit dialog boxes described below will appear, depending upon how the Device Type ▾ of the family has been configured in the Family Edit command.

Branch Circuit Device: Other / Equipment Connection​

When the selected family instance has Device Type set to Branch circuit device: Other, Branch circuit device: Equipment connection, or has not been configured using the Family Edit command, the Instance Edit dialog box below will appear.

tip

If the family instance has been configured using the Family Edit command, many of the fields in this dialog box will include a Family default setting. Fields with this setting will use the same setting as the corresponding field in the family.

  •  Device Type: The Device Type ▾ set for the family in the Family Edit command.
