In some cases, you may wish to temporarily hide certain types of objects from display, such as all demand sites or wastewater treatment plants. Uncheck the box on the WEAP legend next to the type you want to hide. You may hide all objects at once: choose the Hide All WEAP Objects option from the General menu or from the right-click menu on the WEAP legend. Once some or all WEAP objects are hidden, an option to Show All WEAP Objects will be available.
