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
