Polar coordinates
Entry of Cartesian coordinates is expected as standard. With the soft
keys for polar coordinates you switch individual coordinates to polar
coordinates.
You can mix Cartesian coordinates and polar coordinates to define a
point.
Angular input
Select the desired angle input by soft key.
 Linear elements
 AN Angle to the Z axis(AN<=90°—within the preselected
quadrants)
 ANn Angle to the following element
 ANp Angle to the previous element
 Circular arcs
 ANs Tangential angle in the starting point of the circle
 ANe Tangential angle in the end point of the circle
 ANn Angle to the following element
 ANp Angle to the previous element
