- For a Filled Region, go to the Annotate tab, Detail panel, Region...on the Properties dialog, Edit Type, Duplicate, name the new pattern accordingly, and change the information shown below as needed.
- For a Material (either create a new one, or modify an existing one) go to the Manage tab, Settings panel, Materials and on the graphics tab change the color of the patterns as needed.
