Get P-Spline Parameterization Data Example (VB.NET)

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. 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
