# Blend-Point Editor: Y–axis Values

### Blend-Point Editor: Y-axis Values

Two Motion-Values (for each Motion-Derivative).

It is important to know that there are two motion-values at a Blend-Point. There is a motion-value at the:

End of the Previous-Segment

AND

Start of the Selected-Segment.

Also, because there are four motion-derivatives,  there is a total of eight (8) motion-values at each Blend-Point.

Y-axis Values

In the image above, the two motion-values relate to the Position motion-derivative only.

 End Position (of the Previous Segment) = 10mm Start Position (of the Selected-Segment) = 30mm You can see the two motion-values in the position plot and in the End Position and Start Position data-boxes. Note: the Start Position and end-Position are usually forced to equal each other - see Control-Buttons, below.

Control Buttons (for each Motion-Derivative) :

 End Control button - to control the motion-value at the End of the Previous-Segment. This control-button has three(3) states - Do Edit, Do Not Edit, and Can Not Edit Match Control button - to control the flow of motion-values from the end of the Previous-Segment to the Start of the Selected-Segment. This control-button has two(2) states -   Do Force Start of the Selected-Segment = End of the Previous-Segment Do NOT Force Start of the Selected-Segment = End of the Previous-Segment Start Control button - to control the motion-value at the Start-of the Selected-Segment. This control-button has three(3) states - Do Edit, Do Not Edit, and Can Not Edit

#### Example: Y-axis Values: Control-Buttons with EACH Motion-Derivative

In this example, the state of the three Control-Buttons for the Position motion-derivative are:

 EDIT the motion-value ...of the END Position of Previous-Segment DO NOT force the start Position to equal the end Position EDIT the motion-value ...of the START Position  of the Selected-Segment
