+
+        In some rare cases (i.e. "resetting" a model or for security purposes)
+        you may need to purge all relationships and data within a model but
+        retain the ability to view the geometry in a model. This patch purges
+        the following relationships:
+
+        - STEP comments, which may include software export metadata
+        - Header data, which may include filenames
+        - Owner, person, organisation, and application data
+        - Addresses
+        - Rooted names
+        - Tags (that reference original software)
+        - Properties and quantities
+        - Materials
+        - Styles (e.g. colours)
+        - External references like classifications, documents, libraries
+        - Types
+        - Groups (such as model groups or search groups) and systems
+        - Profile names
+
+        Example:
+
+        .. code:: python
+
+            # Watch the world burn
+            ifcpatch.execute({"input": model, "recipe": "PurgeData", "arguments": []})
