To Construct a Seed and Boundary Surface Set
1. Select a surface on your model to establish the surface anchor (seed) surface. Creo Parametric highlights the selected surface.
2. Hold down the SHIFT key and move your pointer over the model. Valid surfaces highlight and a ToolTip displays the surface name.
3. Select a surface that belongs to the same solid part geometry or quilt as the anchor surface. This establishes the boundary surface. Creo Parametric constructs and highlights the Seed and Boundary surface set. Notice that if you are working outside of a tool, the Selected Items area indicates the selection and the Selected Items dialog box contains Seed and Boundary Surfaces. However, if you construct a surface set from inside a tool, the active collector contains the surface set and the Seed and Boundary Surfaces label displays on the model.

You can also use a Loop surface set as a boundary for constructing a Seed and Boundary surface set. To construct a Loop surface set and use it as a boundary for constructing the Seed and Boundary surface set, hold down the SHIFT key and select a two-sided edge that belongs to the selected boundary surface to complete the Loop surface boundary.
4. Release SHIFT. The Seed and Boundary surface set highlights. This set includes the seed surface and all the surfaces between the seed surface and the boundary surfaces but not the boundary surfaces. Notice that boundary surface is not highlighted.
5. If you want to include additional boundary surfaces to the set during the same workflow, repeat step 2 through step 4. Note that most tools require that the surfaces belong to the same solid part geometry or quilt.
6. If you want to construct an additional Loop surface set during the same workflow, release SHIFT. Then, press CTRL and click a surface on your model to establish an anchor for the new surface set. Release CTRL and repeat step 2. through step 4.
7. Open a feature tool or continue working in a feature tool to use the surface set to create a feature.

You can use Next, Previous, or Pick From List from the shortcut menu to select edges.
To open the Selected Items dialog box, simply double-click the Status area next to the Filter box.
In Seed and Boundary surface sets you can use Intent surfaces as bounding surfaces.
