Works fine when you change 6th point with value of 2nd.
analyze comments from 3.5 documentation example, note where is <0,0>
prism {
cubic_spline
0, 1, 7,
<1,-1>, <0,0>, <6,0>, //outer rim; First control is <1,-1> and
<6,8>, <0,8>, <0,0>, //<0,0> is first & last point.
<-1,1>, //Last control of first spline is <-1,1>
}
"In the cubic_spline, each sub-prism needs two additional control points -- one
at the beginning of each sub-prisms' point sequence to determine the slope at
the start of the curve and one at the end. The first point specified is the
control point which is not actually part of the spline. The second point is the
start of the spline. The sub-prism ends when this second point is duplicated.
The next point is the control point of the end of the first sub-prism. Next is
the beginning control point of the next sub-prism. The point after that is the
first point of the second sub-prism."
