Key parameter description 
 Radius = 5 
Radius = 5 in the "move (arc) line" command refers to setting the radius 
of the transition arc between two straight lines R = 5mm, which is used 
to achieve a smooth transition of the arc in a straight motion. 
The parameters of Radius can be set as Radius> 0, Radius = 0, Radius = -
1, different parameters correspond to different trajectories. 
(4) Radius> 0. For example, setting Radius = 5, the turning trajectory is as 
shown in the black arc in the figure below, which can achieve a smooth 
turning effect. 
 
Note: The radius of the arc is smaller than D
AB
 and D
BC
. 
(5) Radius = 0. There is no arc transition at the turn, it will be a sharp turn
