Find Bloated Families living in your Projects

If you want to find out the actual file size of families that are living in your project, follow these steps:

1. In Revit 2012, export all families to RFA files (File - Save As - Library - Family - ). 
   In 2011, you might be interested in this method.
2. View the exported folder in Windows Explorer.
3. Sort By - Size
4. You will see the most bloated families at the top.

Here is an example:

To reduce the size of the largest families, I can now:

1. Open them from the project
2. Delete any unnecessary data (such as imported DWGs)
3. Purge and then 
4. Reload them into the project.

I anticipate significant size decreases for my (currently) 547 mb project!
