BSplineSurface.GetBSplineInfo Method
Parent Object: BSplineSurfaceDescription
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.
Syntax
BSplineSurface.GetBSplineInfo( Order() As Long, NumPoles() As Long, NumKnots() As Long, IsRational As Boolean, IsPeriodic() As Boolean, IsClosed() As Boolean, IsPlanar As Boolean, PlaneVector() As Double )Parameters
| Name | Type | Description |
| Order | Long | Input Long array of two elements that specifies the order of the spline in U and V respectively. |
| NumPoles | Long | Input/output Long that specifies the number of poles. |
| NumKnots | Long | Input/output array of Longs that specifies the number of knots. |
| IsRational | Boolean | Output Boolean that specifies whether the B-Spline is rational. |
| IsPeriodic | Boolean | Input/Output Boolean that specifies whether the B-Spline is periodic. |
| IsClosed | Boolean | Input/Output Boolean that specifies whether the curve is closed. |
| IsPlanar | Boolean | Output Boolean that specifies whether the B-Spline is planar. |
| PlaneVector | Double | Output Double that specifies the B-Spline's plane vector. |
