Get P-Spline Parameterization Data Example (C#)
This example shows how to get P-spline parameter data for a selected
spline or curve.
//---------------------------------------------------------------------------
// Preconditions:
// 1. Open <SolidWorks_install_dir>\samples\tutorial\molds\telephone.sldprt.
// 2. Select a curved edge of Shell1 in the graphics area.
// 3. Rename the namespace to match the name of your C# project.
// 4. Open an Immediate Window.
//
// Postconditions:
// View the following information about the selected spline
//
in the
Immediate Window:
// * dimension
// 1-D: X
// 2-D: X, Y
// 3-D: X, Y, Z
// 4-D: X, Y, Z, W (where W is the weight of the control point)
// * order (degree + 1)
// * periodicity
// * number of knots
// * number of segments
// * coefficients in each segment polynomial
// # coefficients = (segment count) X (dimension) X (count)
// * spline style: color, layer, layer override, line style, line weight
