The Family Replacer in the Families command group can replace family instances of various concerns in the current model (either project or assembly family) with another family, with a few options provided.
Let's take the assembled family that was introduced earlier for example here.
After one chair family instance is picked, the command will pop up the Family Browser dialog for users to choose which family symbol should be the replacement.
As introduced earlier, details can be checked about the family symbol in the right pane. Obviously, one and only one family symbol should be selected in the Family Browser. Otherwise, the command will display a message box after the OK is pressed and quit the process.
If a proper family symbol is selected and the OK pressed above, the Options dialog for the particular Replacer command will show up.
- AllowDifferentCategories: specifies whether to allow families with different categories to be the replacements.
- ApplyToAllInstancesOfSameCategory: specifies whether to apply the replacement to all family instances of the same Category such as Furniture.
- ApplyToAllInstancesOfSameFamily: specifies whether to apply the replacement to all family instances of the same Family such as Chair.
- ApplyToAllInstancesOfSameSymbol: specifies whether to apply the replacement to all family instances of the same Family Symbol such as Chair 30" x 30".
- ApplyToSelectedInstancesOnly: specifies whether to apply the replacement to the selected family instances only.
- KeepExistingParameterValues: specifies whether to keep the values of existing parameters if the replacement has the same.
- KeepExistingPropertiesIncludingLocation: specifies whether to keep the properties of existing instances including the important location.
After the OK button is pressed, the information box of the Family Replacer command will show up.
The model has been properly updated at this moment.
A simple case is demonstrated above. In fact, the Family Replacer can apply to both Family Model and Project Model, which can be very complex and contains thousands of family instances. In the Full Edition, all the replacement options are available.
All of these can be exercised in the free trail edition of Revit Family Organizer.
