Managing the Background Visualization

You can display and filter the visualization of geometric elements contained in a plane or a set of planar geometries in the work area using the App Options panel.

Before you begin: Create a 3D shape containing geometric elements.
  1. In the App Options panel, click Pickable visible background .

    To access the App Options panel, from the Tools section of the action bar, select App Options .

  2. Select a plane.
    A Work on Support is automatically created. If a Work on Support already exists in the same plane, it is activated.



    Important:
    • You can also select a set of elements (for instance two lines) belonging to the same plane in order to determine a plane. If the elements are in different planes, an error message is issued. Note that multi-selection is only available before entering the command.
    • You can also select an annotation text that will be used to determine a plane.
  3. Click Pickable visible background to clear the selection.
    The Work on Support is removed from the tree, if it is automatically created and if there are no geometries created on this Work on Support.
  4. Click No 3D background and a join feature.
    All geometric elements available in the plane of the join feature are visible. All the other elements are invisible.

  5. Click Unpickable background .
    You can only pick the geometric elements that are in this plane.



    Other elements cannot be picked:



  6. Click Low intensity background .
    Geometric elements that are in the plane are displayed normally. However, elements that are not in the plane are displayed with a low intensity (including curves and wireframe elements) but they still can be picked:

  7. Click Unpickable low intensity background .
    Geometric elements that are not in the plane are displayed with a low intensity and they cannot be picked:

  8. Click Lock current view point .
    Now, you can only perform translations in the plane parallel to the screen and rotations along the axis normal to the screen as well as zoom in and zoom out. Note that you must use the mouse to perform these transformations when the current view point is locked.
    Important:
    • Low intensity elements (that are not in the plane) are not displayed in front the plane geometry but behind, even though they are geometrically in front of it.
    • The status (active/inactive) of all the above commands is retained when changing the apps.
    • Visualization modes are temporary, they only act as filters in the work area. They disappear once the command is deactivated.
