extrudePoints peculiarities

[etray]

1.) If you pass a list of points to extrudePoints, it omits the first point. This was not noticeable in the examples, because they had a lot of points. As a workaround, it seems the first point can be put into the list twice.

2.) Some segments seem to be rotated 45 degrees. In this example, the last segment is rotated.

springLength=40;
springWidth=3.5;
springThickness=2;

points=[
        [10,10,springLength+50],        
        [10,10,springLength+50],        
        [10,25,springLength+50],  
        [10,10,+50],
        [10,10,-springLength+50]
       ];
