Gets (by extraction) a curve that follows a constant u or v parameter along the surface. The curve will have the same properties as the surface in the direction of the extraction. For example, when a curve is extracted from the periodic direction of a surface, the extracted curve will also be periodic. The type of curve returned is dependent on the shape the surface.

"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object. |
| Type | Description |
| ObjectCollection | Returns an ObjectCollection that contains one or more curves. Multiple curves are returned when the SurfaceEvaluator is obtained from a Face and the curve cuts across internal boundaries. The resulting curves are trimmed to the boundaries of the Face. When the SurfaceEvaluator is obtained from a geometry object, a single curve is returned because there are no boundaries to trim the curve. The type of curve(s) returned is dependent on the shape of the surface. |
