Arrow annotations/labels
To create a label, press and hold on a structure until an arrow appears. While you continue pressing, drag the arrow to the side and then release. Tap on the created label to bring the menu up.
Labeled structures are available as bookmarks in all the Monash University 3D Anatomy Series, as well in most of the bookmarks of other cases.
Save your labeled structures as a bookmark, by tapping Mannequin > Save Bookmark.
Tapping on an existing label will bring up the label menu. You can change the label color, name, and hide or reveal all labeled text. Select Lock All to be able to hide or reveal all text.
