Creating a Matching Constraint

You can create a matching constraint between the edge of a subdivision and a boundary curve.

Before you begin:
  • Create a 3D shape containing a subdivision surface.
  • Create a boundary curve.
  1. From the Shape Sculpt section of the action bar, click Creation Match Surface .
  2. Select the edge of a subdivision and then select the boundary curve.
  3. Click Apply .
    A matching constraint between the two geometrical elements is created.

  4. From the Tools Palette, click one of the following:
    OptionDescription
    Shape Sculpt Selects the matching constraint to be edited.
    Remove Removes the selected matching constraint.
    Remove All Removes all matching constraints.
    Creation Match Surface Creates a new matching constraint.
    Target Selection Selects the boundary curve of a matching constraint.
    Tangent Propagation Propagates the selected edges in tangency.
    Sharp to Smooth Chooses between a very sharp matching surface or a smooth and curved matching surface. Click this icon to switch from sharp to smooth in tangency, and then smooth in curvature.
    Deform Adds a new ribbon of faces to lower the deformation of the original surface. Click this icon to switch to Add.
    Automatic or Custom Options Provides additional options.
    Cut Defines the number of cuts on your matching surface.
    Ratio Spreads the deformation created by the match.
    Connection Quality Defines the connection quality and continuity of a matching surface.
    Curvature Quality Defines the curvature quality and continuity of a matching surface.
    Mesh View Hides or displays the base mesh.
    Apply Validates the command.
    Notes:
    • You must click Apply each time you use an option.
    • You do not need to create a curve on a surface to make a matching constraint.
    • You can only use the Sharp to Smooth option if you create a matching constraint with a curve that do not lie on a surface.
    • You can work in automatic mode for a more efficient use of the options.
  5. From the Shape Operations section of the action bar, click Isophotes Mapping and then select Analysis mapping on part or element by element .

    This option lets you analyze the quality of the matching constraint you have applied.



  6. Click Curvature Quality and use the slider to modify the reflection quality of your matching surface as desired.
