Fragmenting Curves

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

Open the FreeStyle_Part_23.CATPart document.

  1. Select the curve.

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

The selected curve is previewed with separators indicating the limits of each arc, thus allowing the pre-visualization of the resulting curves.


  The Fragmentation dialog box is displayed.
The Type frame does not apply for curves.

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

  2. Click OK.

The curve is fragmented in as many curves as there were arcs in the initial curve. This means that independent curves are created.

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


  • Multi-selection is available.
  • This function enables you to fragment surfaces as well, see Fragmenting Surfaces.
Available capabilities from the Dashboard are: keep original.
