CATIA V5 – Enhanced Scene (creating a scene)

Tools for creating a scene in an assembly are very useful and simple to use, while at the same time allow to create multiple different assembly configurations. Mastering these tools eases visualization of arranged assemblies on drawings and in many cases reduce drafting time. A big advantage is evident when displaying the sequence of assembly.

Advantages of working with scenes are:

  • Always work in one document
  • It is not necessary to make a copy to show a different configuration or feature of a geometry
  • Using scenes it is possible to create presentation or assembly movie
  • Updating the assembly automatically updates all the scenes as well
  • There is no limit on the number of scenes that can be created, so all details can be visualized
  • The current on screen geometry can be easily changed

 

Limitations in working with scenes:

  • Scenes cannot manipulate geometry, which was not in the assembly before creating the scene. This means that the geometry which we want to manipulate must already be in the assembly, before creating the scene (it can be hidden, but it must be present)
  • If Full overload mode is used, the subsequent changes in geometry will not be reflected in scenes
  • Removing any geometry affects all scenes
  • Scenes are accessible only within assemblies (Assembly Design)
  • The Product needs to be carefully constructed to make scene creation easier, so we need to think about the approach before we start the project

When the scene creation icon is activated ,a new window appears in which we choose Overload Mode, where we have the option of Partial and Full. By turning off Automatic naming, we can assign scene titles.

Partial Overload mode allows subsequent assembly modification (e.g. adding new components), where the changes will be reflected in the scene (new components will be visible in the scene). Contrary to Full Overload Mode which is independent from the assembly and subsequent changes on the assembly will not be visible in the scene.

After the type of scene is chosen by clicking OK, the scene is created. Background colour changes to green. Within the scene tools we can find the icon Explode  with which all parts in an assembly can be separated.  Besides this there is an icon with which we can save the current status, icons with which we can apply scene attributes to assemblies and reverse.

The created scene appears within the tree Applications/Scenes. After the scene is created, it is no longer possible to change Overload Mode (Partial/Full). Inside scenes it is possible to hide individual components, which we do not want to appear on drawings. It is also possible to move parts by using the compass (useful when creating instructions for assembly) or creating Exploded view.

When drafting it is possible to change links for any view from the source assembly to the scene, by right clicking on the view frame and then on Modify links. After this we need to switch to the assembly, click on the scene and return to the draft. In the menu Link Modification the scene appears and by clicking Add all, this view will have a new link to the scene instead of the entire assembly.
