Extracting Sub-Elements

You can extract sub-elements (curves, points, surfaces, solids, volumes and so forth) that are joined into one element.

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

  1. Click Multiple Extract .

    The Multiple 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.

  2. Select the elements to be extracted.

    If the first selected element is a curve (or a point, a surface, a volume), the next selected element is necessarily a curve (or a point, a surface, a volume).

  3. Choose the Propagation type:


    • Point continuity: the extracted element will be created according to point conditions and therefore 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 one or more groups of federated cells according to their connexity.

    Warning:
    • This option applies to all the inputs that lie on the same support.
    • Cells that are not propagated are never federated, even if they are in contact with other federated cells.

  5. Click OK to extract the elements.
