Figure 16
Cartesian coordinate system with 3 axes (X,Y,Z)
Example:
P1 X= 30 Y= 20 Z= 0
P2 X= 30 Y= 0 Z= -10
The specifications of the three axes as well as the three coordinates is done as a so-called clockwise-rotating
system and follows the right-hand-rule (see figure 17). The fingers of the right hand always show to the positive
direction of each axis.
This system is also called the clockwise-rotating coordinate system.
