Adjust Faces is used to create a smooth, tangential connection between faces. While it is better to create smoothly-connected surfaces when creating a part, Adjust Faces can be used to repair poor connections between surfaces.
Adjust Faces works in two different modes along an edge:
• One face - If only one face along a selected edge is modifiable, the surface corresponding to this face will inherit the tangent plane of the adjacent face. Create a smooth, tangential connection between boundary-trimmed (Boundary-trimmed faces end exactly along the edge, or boundary, of the face) faces with non-rational, b-spline geometry. Only one face is trimmed along the boundary edge.
• Both faces - If both faces attached to an edge are allowed to be changed, the corresponding surfaces are modified simultaneously to improve the continuity of the tangency.
Select all the edges in the area that you wish to be smoothed. This should give a better result than selecting only one edge. If problems occur, they may be related to one specific surface. In this case, reduce the number of edges for a better result.
The range specifies the area of the face where the surface will be changed. The range values must be in the interval 0 - 1. The area to be modified extends from the chosen edge until the feedback range curve. If the value of the first Range field (global) is changed, all ranges will be changed.

When Adjust Faces is used with face parts, a new part containing the modified surfaces is created and the original part is unchanged. When Adjust Faces is used with solid parts, the system tries to integrate the new surface into the existing part using the Align function (Modify 3D). If the integration is not possible, the system creates a new part.
To adjust faces,
1. Activate the Surfacing module.
a. Click File > Modules. The Modules dialog box opens.
b. On the Modules pane, click Surfacing under Licensed.
2. Click Surfacing and then, in the Advanced Surfacing group, click Adjust Faces. The Adjust Faces and Select dialog boxes open.
3. Click one or more edges. Visual feedback shows the faces that will be modified and the part of the face to be changed. To change the range of the surface to be modified, type a value in Range (global effect). The feedback lines will move accordingly.
4. To keep a face unmodified and adjust the other face(s) to it, click Keep Faces and select the face(s) to be left unchanged. The yellow line on the face will disappear.
5. To change the range of one face, click Change Range.
a. Select an edge.
b. If two faces belong to an edge, select a face.
c. Type a value in the second Range field (local effect). This range will apply only to the selected edge and face.
If the global Range is changed after the local Range, all ranges will be reset to the new global range value.
6. Use Zebra stripes in Surface Analysis to view the tangential connection between the faces.
7. Click Preview to see a preview of the modified surfaces.
Adjust Faces. The Adjust Faces and Select dialog boxes open.
