Globally Deforming Surfaces

This command is only available with the FreeStyle Optimizer.

This task explains how to deform a set of surfaces in one operation.

Open the FreeStyle_Part_36.CATPart document.
  1. Select the surfaces to be deformed, using the Control key for multi-selection.

  2. Click the Global Deformation icon:
    The Global Deformation dialog box appears, into which you can specify deformation options: using an intermediate patch or a user-defined axis.
    In this case, use the default option: intermediate patch ( Intermediate surface use icon).

  3. Click Run in the Global Deformation dialog box.
    A transparent patch with control points and mesh lines is displayed. It represents the intermediate surface bounding box.
    The Control Points dialog box is displayed. Use it to define the type of operation to be performed on the control points:
    • Support defines the type of translation to be applied.
    • Law defines the type of deformation that is to be applied when several control points have been selected.

  4. Use the control points and the mesh lines of the planar patch to deform it. The space transformation is defined between the initial patch and the deformed patch.
    All surfaces are automatically and dynamically deformed according to this intermediate patch deformation.
    The final deformed surface looks like this.

Open the FreeStyle_Part_37.CATPart document.
  1. Select the surfaces to be deformed, using the Control key for multi-selection.

  2. Click the Global Deformation icon:

  3. Select the 1 guide option.

  4. Click Run in the Global Deformation dialog box.

  5. Select a guiding surface (here the blue surface).
    The Control Points dialog box is displayed.
    Use the control points and mesh lines to deform the surface.
     

  6. Click OK in the Control Points dialog box.
    The deformation is performed along the selected guide.

  7. Select the 2 guide option.

  8. Click Run in the Global Deformation dialog box.

  9. Select two guiding surfaces.
    The Control Points dialog box is displayed. Use the control points and mesh lines to deform the surface.

  10. Click OK in the Control Points dialog box.
    The deformation is performed along the selected guide.
    If you check the Continuities on guide option, the system globally deforms the surfaces while retaining the continuities on the selected guide.
    In our example, the top surface is selected as guide, and the Continuities on guide is checked.
    • When globally deforming re-limited surfaces, i.e. surfaces which limits have been redefined, make sure that you check the continuities between faces. Indeed, depending on the geometrical configuration, it may happen that the set continuities are lost when deforming.
    • Available capabilities from the dashboard are: auto detection, attenuation,  continuity, orders, and keep original.
