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.
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:
|
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. |
