This task shows you how to deform an original shape, e.g.
to take a spring back effect into account.
You will:
The original shape is thus transformed into a new one, by a digitized morphing. The original shape i.e. the Element to deform can be a solid or an open shape andyou can select one or several elements (if you select several elements, Digitized Morphing will create one feature for each input element). The displacement is defined by a vector file. It is a text file that:
You can also define the displacement by selecting a CATAnalysis or a Distance Analysis feature. |

|
|||
The morphing is computed at each point found in the text
file, with the corresponding vector, The information contained in the text file is stored as a
link to the feature that will be created. |

Using a Deviation Analysis Feature - LimitationsA Deviation Analysis feature is not a representation of a deformation of
a shape. It is only a set of vectors resulting of a distance analysis
computation between a cloud of points and a surface: the displacements
created by a Deviation Analysis between two shapes are different from the
displacements to apply to transform a shape into the other one, especially
in the case where the initial shape presents sharp edges or curvature
variations or when the deformation includes a "stretching" of the initial
shape.
|
|||
The shape to deform is
DeformationInput01.CATPart
in the samples directory. The file of vectors used to compute the deformation is DeformationVectors01.txt in the samples directory. The sample is a simple example.
The next task explains how to use a limiting contour. |

Digitized Morphing is available on a part level only. If you are working in a product structure, double-click a part to
activate it before clicking the Digitized Morphing icon . The dialog box looks like this: You can create the result in a new CATPart that will be inserted under
the Product you are working in, |

|

You can select:
|
|||
|
|||
If you have selected several elements to deform, one
feature is created for each element to deform. Result is a set of features or datum entities. |
