either entire families or just unused types. Notice that some of the families cannot be selected
for deletion, because they are either nested in another family or other types of that family are
already being used in your project.

In addition to families, unused materials and property sets can be removed using the Purge
Unused command. Imported categories can be purged as well; however, you don't have the
option to choose which ones to delete.
We don't recommend that you use this command in the early stages of design, because your
file size won't be that large early on, and purging would eliminate any preloaded families that
you might have included in your template. During schematic design and design development,
you are typically going through design iteration and will likely be adding and removing content
regularly. It can become a hassle to have to constantly load or reload families into the model.
If your model is not suffering from performance issues or the file size isn't unruly, it's not
necessary to perform a Purge Unused.
You might also consider using the Save Families tool before purging all unused families.
