Fragmenting Surfaces

In this task you will learn how to fragment multi-segment bodies into mono-segment  bodies.

Open the FreeStyle_Part_33.CATPart document.

  1. Select the surface.

  2. Click the Fragmentation  icon  in the Shape Modification toolbar.

The selected surface shows the limits of each segment in solid lines, allowing the pre-visualization of the resulting surfaces.


The Fragmentation dialog box is displayed.


  1. Choose the breaking options:
    You can decide to break the surface along U, along V or in both U and V directions. 

  2. Click the Keep original icon from the Dashboard if you want to keep the initial surface when fragmenting the body.

  3. Click OK.

The surface is fragmented in as many surfaces as there were segments in the initial surface. This means that  independent surfaces are created.

In the example, we assigned a different color to each of the resulting mono-segment surfaces.

  • Multi-selection is available.
  • This function enables you to fragment curves as well (see Fragmenting Curves).
Available capabilities from the Dashboard are: keep original.
