This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.
In drawing templates this attribute shows the revision mark of the drawing. In
the REVISION lists it also
shows the revision history. This is the revision mark of the revision entered in the
Mark box in the Revision handling dialog.
