When you load a family with many types into a project, use a type catalog to select and load only the types that you need.
This strategy helps decrease project size and minimizes the length of the Type Selector list when selecting family types.
For example, if you load the entire C-Channel structural column family, you must scroll through dozens of C-Channel types in order to make your selection. Simplify the choices by loading a single C-Channel type, such as a C15x40.
The type catalog provides a dialog that lists the available family types that you can sort through and select before you load types into a project.

The Type Catalog displays.
You can select multiple types by pressing Ctrl during selection. You can also narrow the range of search items by selecting specific parameters from the list at the top of each column.
