Using the Smooth Command

This task shows how to smooth positions in a simulation. You recorded a simulation using the space ball and automatic insert capability. You used the automatic clash detection. The smooth command lets you obtain a path without collisions as it removes the useless positions.
Open the SMOOTH.CATProduct document.

  1. In the specification tree, select Simulation.1.

  2. Click Smooth.

    The Smooth dialog box is displayed.
     

  3. Enter 10 mm in the Translation step box.

  4. Click OK.

    This is what you obtain:

  5. Close SMOOTH.CATProduct without saving the modifications, then re-open it (a track is defined).

  6. Select Track.1 either in the specification tree or in the geometry area.

     

  7. Click Smooth .

    The Smooth dialog box appears.

  8. Keep the parameters values listed above, and click OK.

    The track is smoothed.
    Now you are going to play your smoothed track:

  9. Click the Player and select Track.1 in the specification tree.

    Player is active. You can replay your track with respect to:
    • time (in seconds),
    • a specified shot or,
    • path finder or smooth specifications if previously defined (this is the case in our example)

    Player
    You can replay your smoothed track using the pathfinder parameter in the Player list:
    • selecting pathfinder parameter in the drop-down list swaps to the right interpolation (spatial-based interpolation, smooth specification)
    • Alternatively, you can choose to keep the default parameter (time in seconds), but it this case the consistency between the smooth specification and the way it is played are not guaranteed

  10. Click Play Forward to play your smoothed track.
