Making structure(s) transparent: After selecting a structure, tap the "Fade" button on the left side of the screen to make it transparent. You can make all the structures around a selected structure transparent in Atlas views by tapping "Fade Others" under the Actions menu. 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 on the left hand side of the screen to make it invisible. You can make all the structures around a selected structure invisible in Atlas views by tapping "Hide Others" under the Actions menu.
Showing hidden structure(s): Immediately after selecting and hiding a structure, you can restore the structure to the View by tapping the "Show" button on the left side of the screen. In Atlas views, 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 "Show All" under the Actions menu.
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, and back to shown with each two-fingered tap.
Refresh View: You can refresh Atlas views by tapping "Refresh View" under the Actions menu. Refreshing the view restores the camera angle and all structures to their original
