Extracting Elements

You can perform an extract from elements (curves, points, surfaces, solids, volumes and so forth).

This may be especially useful when a generated element is composed of several non-connex sub-elements. Using the extract capability you can generate separate elements from these sub-elements, without deleting the initial element.

Before you begin: Create a 3D shape containing geometric elements.

About the Extraction of Geometry

  1. Click Extract .

    The Extract Definition dialog box appears as well as the Tools Palette. For further information about the Tools Palette, refer to Infrastructure User's Guide : Selecting Using Selection Traps.

    In the Part Design workbench, the Extract capability is available as a contextual command named Create Extract that you can access from Sketch-based features dialog boxes.

  2. Select an edge or the face of an element.

    The selected element is highlighted.

    Important: Multi-selection is available to let you select several elements to be extracted. Note that it not available at edition.

  3. Choose the Propagation type:


    • Point continuity: the extracted element will not have a hole.


    • Tangent continuity: the extracted element will be created according to tangency conditions.


    • Curvature continuity: the extracted element (necessarily a curve) will be created according to curvature conditions.


    • No propagation: only the selected element will be created.

  4. Select the Federation check box to generate groups of elements belonging to the resulting extracted element that will be detected together with the pointer when selecting one of its sub-elements.

    For further information, see Joining Surfaces or Curves.

  5. Click OK to extract the element.

    The extracted element (identified as Extract.xxx) is added to the specification tree.
