Library

The Library tab lists all family types in the user's libraries. If no user library exists upon opening the Library Browser, tallyCAT will automatically create the Default library and populate it with a few test items.

By default, this library will be created in the following location: C:\Users\[UserName]\AppData\Local\C-Change Labs Inc\tallyCAT\Libraries\Default

In the filesystem a library is a folder containing various RFA and RVT files hosting Revit family types. It is indexed by a special tallyCAT Library Indexer background application which stores the collected data in a database from where the tallyCAT Library Browser could read it.

If for some reason no library currently exists, the Library tab will look as follows having only the Add Library button.

The Add Library button will bring up the Library Settings window where you could add a library. More information on it is provided below.

Otherwise, the fully functional Library tab will be displayed.

Here in the data grid, the Category, Family and Type columns display the corresponding Revit information. The Version column shows off the family type version. The Library column specifies the name of the library where each of the family types resides. If elements of a family type were previously exported to the EC3, the corresponding back annotations were added to the family type. The EC3 column shows whether these annotations are present. If that’s the case, the Unit column will display the quantity unit assigned to the family type on the EC3, and GWP Achievable and GWP Conservative columns will show off the approximate GWP values for 1 unit of this family type (calculated using the Revit material data and the EC3 material statistics).

The right pane displays the same family type information as the one in the Current Project tab. The data grid filters also work in the same way.

The toolbar above the data grid hosts a number of buttons which allow you to perform various actions on project family types. Most of them become enabled when data grid items are checked using the checkboxes in the first column.
