Sensitive Element Redaction allows you to narrow down the full model by removing elements with the selected Data Markings. Additionally, you can choose to remove all Data Markings from the model and save it as a separate project. You can also use the preview function prior to performing the Sensitive Element Redaction.

The preview and the result of a model transformed via Sensitive Element Redaction by selecting the Restricted (R) Data Marking.
This removes all elements with the Restricted (R) and all the higher Data Markings from the Security Classification category (Confidential (C), Secret (S), and Top Secret (TS)).


The model is transformed based on the selected Data Marking and its position within the order of its category. Selecting a Data Marking that is lower within the order of its category means that the elements with higher Data Markings will also be removed from the model. See the example above.
