Thanks Karsten and Cermotan_Tudor!
Both possibilities work, so that I can teach an old CNC system new movements.....

The shape should be round, but this can only be done by defining the points in the old TPA (Italy) program.
Angles must be quantified for a tangential milling form.

Is there quicker method to get the tangential angles from the program?
I did it with contructing rectangels and angel measurement.

But it helped me a lot to find the coordinates of the points.
Thanks for your help.
