For a standard cubic spline use order == 4.

The start and end tangents are vectors that can go any direction. Setting start tangent to a vector from the first to second point will flatten out the start of the curve.

To get a better idea, run the spline command in Autocad and after drawing a few points hit the space bar to specify a start tangent. Drag the cursor around and watch what it does to the curves.

Here is a short and sweet URL defining splines, http://astronomy.swin.edu.au/~pbourke/curves/spline/
