Sensitive Element Redaction

On this page:

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)).
