When there is ONE segment - the segment is always the Selected-Segment
It is easier to use the SEGMENT-EDITOR when there is only one segment in your motion.
Edit a motion with one segment.
The Motion-Law is a 'Flexible Polynomial'. This means, I can edit the 'Start' and 'End' motion-values of all four motion-derivatives individually. There are eight motion-values in total.
In the image below:
Remember - the graphs auto-scale. Therefore, look at the Y-axis to see the minimum and maximum values, as you edit the motion-values.
Part 2: Experiment with the Motion-Values and Control-Buttons
Remember - the graphs auto-scale. Therefore, look at the Y-axis as you edit the motion-values.
Continue to observe the motion values in the data-box and the motion in the graphs.
