Fitting The Surface To a Cloud of Points

This task explains how to fit the deformed surface to an existing cloud of points.

The RoofStart.CATPart document still is open from the previous task.

  1. Select the roof patch as the source element.

  2. Click the Fit to Geometry icon
    The Fit To Geometry dialog box is displayed and texts indicating the fitting constraints are displayed on the surface boundaries provided the Continuity icon is active in the Dashboard.

  3. Set the following parameters in the dialog box:
    • set the fitting tension to 0.5 and smoothing to 0.3.
    • make sure the Impose direction option is unselected.
    • and from the Dashboard, click the U, V Orders icon and make sure they are Nu=4 and Nv=4

  4. Select the Cloud of points as the target element.
    It may be easier to select it from the specification tree than from the geometry itself.

  5. Click Fit in the Fit To Geometry dialog box.

  6. Click OK in the Fit To Geometry dialog box.
