Surface Curve Adaptor Property Editor

Identifies a curve on a surface. It is created automatically when you perform modeling operations (e.g., Loft) with surface curves like isolines, boundaries, etc.

To display: Select the generated surface then click Selection on the Select panel, click the icon for the generator operator (e.g., Loft), and click the appropriate Surface Curve Adaptor tab.

NoteThe parameters displayed depend on whether the curve is an isoline, knot curve, boundary, surface (projected), or trim curve. Not all of the following parameters are displayed at once.

Subsurface Index	Identifies a subsurface by its index, if the surface is a mesh composed of multiple subsurfaces. For simple surfaces with no component subsurfaces, this value is 0. Setting this value out of range may cause unpredictable results.
Position	The position of the curve in the surface's parameter space. This value depends on the surface's parameterization. For example, if this value is 0.5 and the parameterization is uniform, the surface curve lies along the middle isoline (or midway between the middle isolines if there is an even number).
Boundary	The boundary of the surface to use: Min U Boundary (Red). The U = 0 boundary of the corresponding surface. When NURBS Boundaries on the Attributes tab of the Camera Visibility Property Editor is on, this boundary is displayed in red. Min V Boundary (Green). The V = 0 boundary of the corresponding surface. When NURBS Boundaries is on, this boundary is displayed in green. Max U Boundary. The maximum U boundary of the corresponding surface. Max U Boundary. The maximum V boundary of the corresponding surface.
Surface Curve Index	Identifies a trim or surface (project) curve by its index.
Shift	Shifts the U = 0 position along the curve. This option works only with closed curves.
Invert	Reverses the curve's parameterization. The minimum U boundary becomes the maximum U boundary.
