Hello,
thanks for your interest - in my last posted script I have a function "bezier spline". This function doesn't do anything special, just a few vector calculations. Then it returns vector Copy_c which is printed by the panel.

The strange thing I don't understand is:
When I exclude/include the marked line the result will change - but this calculation seems to have absolutely nothing to do with vector Copy_c.

P.S. You can ignore the variables Travel_Speed and Smoothness.
