Linking Geometric Elements to a Subdivision Surface

You can associate geometric elements to a subdivision surface. Geometric elements can be used to modify complex subdivision surfaces with more control.

Before you begin: Create a 3D shape containing a subdivision surface and a geometric element (point, line, or curve). For more information, see Creating Features from Sketch Mode.
Note: A 3D subdivision box and a line are used in this procedure.
  1. From the Subdivision section of the action bar, click Link .
  2. In the Link dialog box, select the geometric elements to associate to the subdivision surface.

    Note: You can select sketches entities and curve features.

    The selected elements are highlighted in green and the constraint icon appears next to them.

  3. Select the subdivision elements to associate to the geometric elements.

    Note: You can select vertices, edges, and faces.

    The selected elements are highlighted in green. The link between the elements is represented by blue dotted lines.

  4. Click .
    The subdivision surface is linked to the selected geometric elements. In the tree, the icon appears next to the linked subdivision surface.
  5. Move the geometric entities to modify the subdivision surface.


  6. Optional: To edit the selected subdivision elements, click the constraint icon and select Edit Link.
    The Link dialog box appears, letting you update the subdivision elements to link.
  7. Optional: To delete the link, click the constraint icon and select Delete.

    Note: If every link is deleted, the standard subdivision surface icon is displayed again in the tree.
