    The Patch command creates a surface, also called a boundary patch, that replaces a missing face.

    Use Patch to replace a missing face on a quilt, or create a face on an opening in a solid. You can create boundary patches to form a continuous quilt or create a solid. The missing face must have a connected series of edges that forms the boundary of the patch.

    If the edges are not coplanar, the patch surface adds curvature to create a blend between the edges. You can control the curvature at each edge to produce a smoother surface.

    Create a surface

    1. Switch the toolbar workspace to Surface.
    2. Click Patch on the Surface pull-down.
    3. In the graphics area, select the edge of a missing face or an opening on a solid. All of the connected edges are automatically selected to create a closed profile.
    4. Select the transition between the patch and the edges.
      • Connected Creates a surface with G0 edges (the new surface edges are connected at an angle).
      • Tangent Creates a surface with G1 edges (the new surface edges are tangential).
      • Curvature Creates a surface with G2 edges (the new surface edges are blended with continuous curvature).
    5. Right-click then click OK to create the surface.

    Patch dialog box

    Selection

    Enables the selection of edges.

    Enable Chaining

    When enabled, clicking a single edge selects all adjacent edges.

    Connectivity

    Controls the transition between the patch and the selected edges.

    • Connected Creates a surface with G0 edges (the new surface edges are connected at an angle).
    • Tangent Creates a surface with G1 edges (the new surface edges are tangential).
    • Curvature Creates a surface with G2 edges (the new surface edges are blended with continuous curvature).
