| Name | Description |
| add | Creates a new fitted spline through the specified points. |
| addByNurbsCurve | **RETIRED** Creates a new fitted spline using the input NurbsCurve3D to define the shape. Fit points are created to create a curve that exactly matches the input curve. |
| classType | Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType(). |
| item | Function that returns the specified sketch fitted spline using an index into the collection. |
| Name | Description |
| count | Returns the number of fitted splines in the sketch. |
| isValid | Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference. |
| objectType | This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object. It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType(): |

| SketchFittedSplines.add | Demonstrates the SketchFittedSplines.add method. |
| Sketch spline through points creation and relative functions API Sample | Create a sketch spline with points and use some operations for spline tangent handle & curvature handle. |
