Making structure(s) transparent: After selecting a structure, tap the "Fade" button under the virtual joystick to make it transparent. You can also use the "Fade" button in the Actions menu. To make all the structures around a selected structure transparent, go to the Actions menu and tap "Fade Others." If no structure is selected, the "Fade Others" button makes all of the structures on screen transparent.
Hiding structure(s): After selecting a structure, tap the "Hide" button under the joystick to make it invisible. You can also use the "Hide" button in the Actions menu. To make all the structures around a selected structure invisible, go to the Actions menu and tap "Hide Others."
Showing hidden structure(s): Immediately after selecting and hiding a structure, you can restore the structure to the View by tapping the "Show" button in the top left corner of the screen or in the Actions menu.
If you have performed other actions after hiding a structure (and it is therefore no longer selected), you can show all faded or hidden structures in the original View (along with any others you may have added to it) by tapping the "Show All" button in the Actions menu.
See the "Search Structures" tab for instructions on showing structures identified by name.
Toggling between show, fade, and hide for selected structure(s): After selecting one or more structures, use two fingertips to tap once anywhere on the screen. The structures toggle from fully shown, to faded, to hidden, back to shown with each two-fingered tap.
