Refit Surfaces and Curves

This task explains how to adapt the shape of surfaces or curves to support elements.
Open the RefitSurface.CATPart document.

  1. Click the Refit icon .
    The 'Refit' dialog box opens.
You can define the following options:
  • Refit-Type:
    • Single Cells: For the Refit operation can only be selected mono-cell elements.
    • Multiple Cells: For the Refit operation can be selected multi-cell elements (joins).
  • Elements: Selection of the elements to be refit.
  • Support: Selection of the supports to which the elements shall be refit.
  Options tab
 
  • Proj. Direction: This option is used to define the direction in which the elements shall be projected onto the support elements.
    • Normal: The normal of the support defines the projection direction.
    • View: The projection direction is the Z axis of the view plane.
    • Direction: An individual projection direction can be defined in the 'Direction' field.
  • Parameter:
    • Max. Dist.: If the check button is switched on, the Refit calculation includes only support elements with a distance to the original elements smaller than the value specified in the text field.
  • Options:
    • Crop Result: If the selected elements are faces (trimmed surfaces), the underlying surfaces are cropped to the size of the faces. When projecting oversize elements onto a small support, a better result will be created using this option.
  See Approximation tab
  See Output tab
  Click onto the 'More Info' button to display deviations and output results.
 
  • Display: Depending on the options selected, values are displayed in the graphics area.
  • Deviation: Indicates the maximum deviation of the Refit result from the support.
  • U+V: Display of the UV vectors of curves and surfaces.
  • Output Result: See Output Result
