There are two assigning methods: Uniform assignment and arbitrary coordinate assignment.
[Uniform assignment]
Valid stroke of the axis will be evenly divided and assigned to the stations.
<For rotary axis>
One rotation (360°) of the rotary axis will be evenly divided to determine the stations. (Maximum number of divisions: 360)
