Preparing the Initial Surface

In this stage of the tutorial, you remove the original wing from the car and import a new wing that is in a different position. These steps create several problems on the geometry surface, which you fix at later stages of the tutorial.

To delete the original wing:
  1. Expand the Geometry > Parts > Car > Surfaces node.
  2. Delete the Strut and Wing part surfaces.
    Deleting the original wing leaves a hole in the surface mesh.

    You fix this hole using the fill holes operation in a later stage of this tutorial.
To import the new wing:
  1. From the menu bar, select File > Import > Import Surface Mesh.
  2. In the Open dialog, select pbm_wing1.x_b from the [INSTALL_DIR]/doc/startutorialsdata/mesh/data directory and click Open.
  3. In the Import Surface Options dialog, set the following properties:
    Property Setting
    Tessellation Density Very Fine
    Open Geometry Scene After Import Deactivated
To add the imported wing to the Graphics window:
  1. Drag and drop the Geometry > Parts > Wing node onto Geometry Scene 1.
  2. In the Select Displayers dialog, select Existing Displayers > Surface 1 and click OK.
  3. Drag a drop the Wing > Curves > Edges node to Geometry Scene 1.
  4. In the Select Displayers dialog, select Existing Displayers > Outline 1 and click OK.
  5. Save the simulation.
The new wing intersects the car body surface, resulting in pierced faces on the surface. You fix the pierced faces by wrapping the external surface of the entire vehicle at a later stage of this tutorial.
