Creating and Cleaning of View Filters  

• Display filters define a list of elements to display and possibly overload while the remainder of the background is hidden.
• Mask filters define a list of elements to overload while the remainder of the background is displayed in the same way as defined in 3D.

In the Visualization toolbar, make sure that the Display Backgrounds as Specified for Each View icon is active.

1. From the layout window, right-click the Front view from the geometry area or from the specification tree, and select Filter > Layout View Filters.... The Layout View Filters dialog box is displayed, enabling you to create filters.

   You can also: Select Filter > Edit Filter: Default to start editing directly the filter that is applied to the view by default (or whatever filter is applied to the current view). Multi-select views to create a filter that will apply to several views. Launch the Layout View Filters dialog box directly (without right-clicking a view first) using Tools > Layout View Filters... Whichever method you choose, any filter can be applied to any view in a layout. To apply an existing filter to a specific view, use one of the following methods: Right-click the view or views and select Filter > Layout View Filters.... From the Layout View Filters dialog box, select the chosen filter and click Apply. Click the view or views and select Edit > Properties. On the Visualization tab, select the chosen filter from the Filter list and click OK. Refer to Editing View Properties for more information. To edit a filter name in the Layout View Filters dialog box, select the filter name and then click it.

   The Layout View Filters dialog box contains the following buttons:

   • Display filter...: Creates a new display filter.

   • Mask filter...: Creates a new mask filter.

   • New from...: Creates a new filter of the same type (Display or Mask) as the selected filter.

     Once created, this filter is not associative with the original filter.

   • Delete: deletes the selected filter or filters.

     This button is not available if you accessed the Layout View Filters dialog box through the contextual menu of a view.

   • Clean up: deletes all the unused filter or filters.

     The Clean up option is available only when the Layout View Filters... command is launched through Tools option. When launched through the contextual menu, in the Layout View Filters dialog box the Clean up option is grayed out. The default filter is never deleted.

   • Edit...: Lets you edit the characteristics of the selected filter through the Edit Filter dialog box.

   • Apply: Applies the selected filter to the selected view without exiting the dialog box.

   • OK: Applies the selected filters and exits the dialog box.

   • Close: Exits the dialog box without validating your changes.

2. Click the Display filter... button. The Edit Filter dialog box is displayed, and a display filter named Filter.2 is created. You can edit this name if you want.

   The Edit Filter dialog box contains the following fields and buttons:

   • Name: lets you edit the name of the filter.

   • Visualization: lets you choose the visualization type that should be applied to the selected elements.

     The various visualization types are:

     • Standard: shows both the 2D and 3D backgrounds.

     • Unpickable: prevents selecting all elements in both the 2D and 3D backgrounds, even though you can see them. You can just handle 2D elements, which belong to the current view.

     • Low-intensified: dims all elements in both the 2D and 3D backgrounds.

       When material is applied to a geometry, this option hides the material type.

     • Unpickable low-intensified: dims all elements in both the 2D and 3D backgrounds. Additionally, although you can see these elements, you cannot select them. You can just handle 2D elements in the current view.

   • Add mode : adds to the list the elements you select in the specification tree or in the geometry area, and filters them according to the visualization type selected in the Visualization list.

   • Remove mode: removes from the list the elements you select in the specification tree or in the geometry area.

   • Select mode: lets you select elements and change their visualization type in the Visualization list.

   • Switches to Tools Palette: transforms the Edit Filter dialog box into a Tools Palette containing the same commands as the dialog box.

     In the Tools Palette:

     • The Switches to dialog box icon transforms the Tools Palette into the Edit Filter dialog box.

     • The Validates command icon validates your modifications and closes the Tools Palette.

3. For the purpose of this scenario, you will create a filter that prevents PartBody from being selected using its 3D background and that dims it.
   Select the Unpickable low-intensified visualization type and make sure the Add mode is active.

4. Select PartBody in the specification tree. PartBody is now added to the filter and the Unpickable low-intensified visualization type is applied to it.

5. Click OK to validate and exit the dialog box.

6. Create more number of filters.

7. Back in the Layout View Filters dialog box, select Filter.2 from the Layout View Filters dialog box and click Apply.

8. Click OK. The dialog box is closed and the newly created filter is applied to the front view. Note that you cannot select the PartBody via the 3D background and that it is displayed using a dimmed color.

9. Select Tools > Layout View Filters.... The Layout View Filters dialog box is displayed.

10. Click Clean up to delete all the unused filters.
    All the filters that are going to be deleted are highlighted.

    A confirmation message box is displayed asking you to confirm if you want to delete all the unused filters:

    Click Yes to confirm.
    In the Layout View Filters dialog box, you can see that only the Default filter and the filter that has been applied (Filter.2) are displayed. All the other unused filters are deleted.
