BLEND-POINT EDITOR : X-axis Values

When you edit the X-axis value of a Blend-Point, you change the Segment-Width of the Previous-Segment and the Selected-Segment.

You do NOT change the Motion-Width.

Please read : Warning - “Bumping” Blend-Points.

X-axis Values

X-axis values of Blend-Point #3

Motion Start

Edit the Motion-Start value to move the motion along the X-axis.

When you edit Motion-Start value, you also the X-axis value of the Blend-Point #1.

X-axis

Edit the X-axis value to move the active Blend-Point along the X-axis.

The Segment-Width of the Previous-Segment and the Next-Segment change.

Note:

You do not change the Motion-Width when you edit the X-axis of a Blend-Point.

The other Blend-Points do not move. However, see SPECIAL CASE and WARNING

Special Case

X-axis value of Blend-Point #1

Blend-Point #1

•Edit Motion-Start to edit the X-axis value of Blend-Point #1.

However:

If you attempt to increase the X-axis value Blend-Point #1 (move it to the right) ...

... you increase the Segment-Width of the Previous-Segment and decrease the Segment-Width of the Selected-Segment.

If you attempt to decrease the X-axis value of Blend-Point #1 (move it to the left) ...

... you decrease the Segment-Width of the Previous-Segment and increase the Segment-Width of the Selected-Segment.

WARNING

“Bumping” Blend-Points !

If you edit the X-axis value of a Blend-Point and it bumps into an adjacent Blend-Point (left or right):

•the active Blend-Point AND the adjacent Blend-Point move together along the X-axis.

•AND the Segment-Width of the Previous-Segment (or Next-Segment) will be very short (e.g. 0.0000036 degrees) and the short Segment is invisible to you in the motion plots.

•AND the Motion-Width will increase by a small amount (e.g. the Motion-Width increase to 360.0000036 degrees).

You can only use the Segment Editor to edit the Motion-Width. You must edit the Segment-Width of at least one segment.

EXAMPLE:

Motion-Start and X-axis Value of Blend-Point #3

Blend-Point Number

The number of the active Blend-Point at the start of the Selected-Segment.

In the image, the Blend-Point number is #3

X-axis values

Motion Start is the X-axis value of Blend-Point Number 1.

Motion Start is at 0 degrees.

X-axis value of the Blend-Point (#3)

X-axis value of Blend-Point #3 is 180 degrees.

As you edit the X-axis value of Blend-Point #3, it moves to the left(<) or to the right(>).

Also, be careful that you do not “bump” the Blend-Point into a Blend-Point to its left of right.

For “bumping”, see WARNING, above.
