Use the Match Edge command to modify a face so it is geometrically continuous with one or more reference objects.
You can: Match the edge of a face to the edge of another face, the interior of another face, or a curve. When the Associative Freeform Editing preference is enabled, the relationship with the parent object is maintained when the parent object is re-positioned.
Maintain or edit the surface degrees and patches. Edit the surface poles while maintaining matching continuity.
Use Shape Control to influence the magnitude of change in the Matched surface.
This example shows two input surfaces during a Match Edge operation, and the matched surfaces. The Match Edge command creates a Match Edge feature in the Part Navigator when the Associative Free form Editing preference is enabled.
