Use the Stratigraphy Types Table's Edit | Turn Off Unused Stratigraphy tool to scan the borehole database and turn off those formations not currently referenced in the project database. This can be a handy way to keep unused formation names from being displayed in diagram legends, to reduce the number of formation names linked to the stratigraphy data tables, and to flag those types that can be deleted from the Types Table.
! The unused formations will not be removed from the Table, but simply listed without a check-mark in the Show in Legend column.
! You can tell the program to NOT model disabled formations in the Stratigraphy modeling settings.
RockWorks will scan the project's Stratigraphy data tables to determine which types are referenced there. All un-referenced formations will be shown without checkmarks from the Show in Legend column in the Stratigraphy Types Table.
