Graphical manipulators are convenient for moving, changing orientations, and resizing entities where applicable. Only one manipulator can be active at any time (be it for section cuts, streamline rakes, or image planes). Since the manipulator modifies a specific item, like a section cut out of many section cuts in the model, the context to show or hide is dependent upon certain rules.
| • | A manipulator is displayed every time a new entity (section cut, streamline/rake, image plane) is created. If a manipulator is already shown on the screen for another entity, the creation process will hide that manipulator and display the manipulator for the new entity. |
| • | The manipulator is automatically hidden every time the display of the entity to which it is attached is turned off. |
| • | Context Menu > Show Manipulator: |
| - | If the individual item is not currently displayed, the manipulator and item are turned "on" using the Show Manipulator context menu option. |
| - | If a manipulator is displayed elsewhere, the context menu activation will hide the old item and make the current object and its selection the active one. |
| - | Once activated using the context menu, the manipulator display can be turned off by using the Hide Manipulator right-click context menu option or whenever a new entity (section cut, streamline/rake, or image plane) is created. |
| • | Context Menu > Hide Manipulator: |
| - | Available in the graphics area right-click context menu. Turns off the display of any manipulator that is currently active. |
