Creating Scenes

	This task shows you how to create scenes. Scenes enable you to: work on the evolution of an assembly in a separate window from the actual assembly and to impart updates to the assembly as you see fit. save a copy of an assembly in a separate window, work on the evolution of that assembly directly on the assembly, and to revert to the saved copy if you are not satisfied with the modifications (in this usage, modifications can be replicated in the assembly using the command Applying a Scene in an Assembly. You can modify the following attributes either in the scene or in the assembly without the modifications being replicated in the other: the viewpoint the graphical attributes of the components the "show" or "hide" state of the components the "active" or "not-active" state of the components
	Overloading of graphical attributes and show / no show state is limited to Products, i.e. these modifications are not replicated between scene and assembly for Products, however, for parts and models, these modifications will be replicated (modifications on parts and models are always replicated in both directions).
	The modification of component position is treated as follows: modification of component position in the assembly is replicated in the scene as long as the components are synchronized for this scene modification of component position in the scene is not replicated in the assembly and also has the effect of de-synchronizing all components having the same parent as the moved product Scenes are identified by name in the specification tree and by a graphical representation in the geometry area.
	When you create a scene, the data that will constitute the scene is a function of the current selection in the specification tree. There are three different possibilities: if no element is selected in the specification tree or if the selected object in the specification tree is the root product, then the newly created scene will include the data of the entire assembly if a sub-product of the assembly is selected in the specification tree, then the newly created scene will include only the data of that sub-product if an existing scene is selected in the specification tree, then the newly created scene will be a copy of that scene
	The following operations are not allowed in scene context: add remove replace cut delete paste
	Constraints are not currently managed by scenes, i.e. creation or modification of constraints in an assembly are always replicated in the scene, even if the assembly and the scene are desynchronized, however the visual consequences of the application of the constraint in the assembly are not replicated.
	Note that you can change the scene background color at any time using `Tools->Options-> Digital Mockup-> DMU Navigator.`Please refer to Customizing DMU Navigator Settings.
	Open a new CATProduct document and insert the following sample model files: (they are to be found in the online documentation folder under cfyug\samples). ATOMIZER BODY1 BODY2 LOCK NOZZLE1 NOZZLE2 REGULATOR TRIGGER VALVE REGULATION_COMMAND
	Note: Creating scenes from components multi-selection is not supported.
	1.	Click the Create Scene icon . The Edit Scene dialog box and a scene representation in the document window are displayed.

	2.	Click Ok to end the scene creation. You are now in a scene window: The background color turns to green. Scene 1 is identified in the specification tree.

	3.	Perform the required modifications. For instance modify: - viewpoint - graphical attributes - show-no show
		Within a scene, click the Reset selected products icon to reposition the components as they were in the initial product. Note that color attributes and the show-hide specification are not taken into account when using the Reset selected products icon.
	4.	Click the Exit From Scene icon to swap to the initial window. The scene is updated to reflect any changes made.

	5.	Double-click Scene 1 either in the specification tree or in the geometry area to swap to the scene window.
	6.	Create as many scenes as needed.
		Note that the scene stamp found at the bottom-left of the DMU Navigator window is for indicative purposes only. It is updated only when you exit the scene.
		Deactivating `View -> Scene Specification` `Visible` in the menu bar removes the scene representation and lets you use the entire screen for the product. You can also use the F4 key to toggle more quickly.
