BSplineCurve Object
Description
The BSplineCurve object is a mathematical utility object that represents a NURBS curve. It is a transient object that is never shown graphically or saved in the Inventor document
Methods
| Copy |
Creates a copy of this BSplineCurve object. The result is entirely independent and can be edited without affecting the original BSplineCurve object. |
| ExtractPartial |
Creates a new curve by extracting a portion of an existing curve. |
| GetBSplineData |
Get the data defining this B-spline. |
| GetBSplineInfo |
Gets general information about the definition of the spline, including its order, number of poles and knots, and its rational, periodic, closed, and planar states. |
| PutBSplineInfoAndData |
Sets the definition data of the spline. |
| Split |
Creates two new curves that are the result of splitting this curve at the specified point. The original curve is left unchanged. |
Properties
| Evaluator |
Property that returns an evaluator object for the curve. The evaluator supports general curve evaluation functions. |
| PoleAtIndex |
Property that returns the x, y, z position of a specified pole. |
