Deforming Elements According to
Surface Wrapping

This command is only available with the Generative Shape Optimizer product.
This task shows how to deform elements basing the deformation on the projection of the element to be deformed onto two definition surfaces.
Open the WrapSurface1.CATPart document for the 3D and Normal types and the WrapSurface2.CATPart document for the With direction type.
 
   
  Here is the initial data for 3D and Normal types Here is the initial data for With direction type

  1. Click Wrap Surface .

    The Wrap Surface Deformation Definition dialog box is displayed.

  2. Select the surface or the curve as the Element to deform.
    Here we selected Surface 1.

  3. Select Surface 2. as the Reference surface.

  4. Select Surface 3. as the Target surface.

  5. Select the Wrap type:

    3D Wrap
    The following picture explains how the deformation is computed in relation to the entered data, i.e. reference/target surfaces:

    Normal Wrap
    The following picture explains how the deformation is computed in relation to the entered data, i.e. reference/target surfaces:

    With Direction
    The following pictures explain how the deformation is computed in relation to the entered data, i.e. reference/target surfaces and deformation direction:
    =>
    The deformed point is computed as follows: Q = P + (Pts - Prs)
    You need to select a deformation direction (here Plane.1):

  6. Click OK to create the deformed element.

    The element to deform is put in no show.
    The element (identified as Wrap surface.xxx) is added to the specification tree.

  • When the definition surfaces (reference or target surface) are too short to allow the projection of the element to deform, these surfaces are automatically extrapolated providing they are mono-cell.
  • The size of the deformed element may not be identical to that of element to be deformed.
  • Reference and target surfaces must be made up mono-cell elements for the 3D and Normal types, however they can be made up multi-cell elements for the With direction type.
