Insert a face part
The Insert function creates faces by interpolating from a set of boundary curves. In Creo Elements/Direct Modeling you can create standalone Face parts which are composed either of single faces, or a combination of faces. When the faces of a face part form an enclosed structure, without gaps between the faces, Creo Elements/Direct Modeling automatically generates a solid part.
You can insert a face by specifying its boundary edges. These boundary edges can be either the edges of a solid part, the edges of a face part, 2D geometry, or 3D curves.
When inserting new faces you may also need to delete other faces or to split edges in order to specify new boundaries.
The Smooth option creates a smooth transition to the neighboring surface when the selected edges pass smoothly into the neighboring surfaces.
To insert a face part,
1. Click 3D Geometry and then, in the 3D Surface Tools group, click Insert Face. The Insert Face and Select dialog boxes open.
Alternatively, select a face part in the viewport and click on the Command Mini Toolbar.
* 
The Select dialog box appears only if an active part exists in the viewport.
2. If necessary, specify the part.
3. Specify the edges of the face you want to create.
4. Click End in Select.
5. Click to complete the operation.
Restrictions
When creating non-planar faces, the maximum number of edges that can be selected is six. There is no limit for planar faces.
Faces with inner boundaries cannot be defined.
Boundaries that are open at the ends are automatically closed by a straight line.
Tangential edges are treated as a single edge when the vertex is the same.
If you delete a blend with Delete and then recreate it with Insert, the new face cannot be modified with the Modify Blend command.
