Splines

Splines automatically draws a curve, similar to a Bezier curve, through a series of points.

To use Splines:

  1. Select Construct tab > Curves panel > Other Methods > Spline/Interpolation to enter Splines mode.
  2. Click the Options button in the dialog bar to switch between the four spline modes which determine whether the curve is an open or a closed interpolation and an open or closed spline. The active spline mode is displayed next to the Options button.
  3. Pick or enter the location of a series of points.

    A preview of the curve is displayed in the graphics window.

  4. Click the Create button to create the curve.

The table below shows the effect of the different spline modes:
