How do I edit the End of the Last Segment?

A question that is frequently asked is:

'How do I edit the 'End of the Last Segment?'

It is easy!

First, make a note of two types of motion:

Non-Progressive: The position at the end of the last segment is the same as the start of the first segment.
Progressive: [also called Indexing]. The position at the end of the last segment is NOT the same as the start of the first segment.

When you use a Flexible Polynomial Motion-Law, you can use the same procedure to make the Velocity, Acceleration and Jerk Values different to each other.

How to...

Edit the End of the LAST Segment.

Non-Progressive

The position at the end of the Last Segment is the same as the position at the start of the first segment.

1.Make the FIRST Segment1s-red the Selected Segment.

Note: the Blend-Point No is '1'6s .


As usual, the Blend-Point Editor can edit the

'End of the Previous Segment' - this is the end of the motion, AND the end of the LAST Segment.
'Start of the Selected Segment - this is the start of the motion.

2.Make the Match Control-Button a Solid Green Circle 2s - see image below
3.Make the Specify-End Control-Button a Solid Black Triangle3s  - see image below
4.Edit the motion-value in the data-box5s

The Position at the end and start3s of the motion are the same, and are equal to the value in the data box5s.

The position at the end of the Last Segment is NOT the same as the position at the start of the first segment.

1.Make the FIRST Segment1s-red the Red Selected Segment.

Note: the Blend-Point No is '1'6s.


As usual, the Blend-Point Editor can edit the

'End of the Previous Segment' - this is the end of the motion, the end of the LAST Segment.
'Start of the Selected Segment - this is the start of the motion

2.Clear the 'Match Control Button2s so it is a 'clear circle'2s
3.Make sure the Specify-End3s and Specify-Start4s Control-buttons are Solid-Black Triangles

When the Triangles are Black, you can specify their motion-values.

The Radio Buttons5s are active. You use the Radio Buttons to edit the Start of the Selected Segment or the End of the Previous Segment.

To Edit the Motion-Value at the End of the Last Segment

4.Click the Radio-Button that is above the 'Specify-End'3sControl-Button.
5.Edit the motion-values in the data box6s

When you edit the motion-value in the box, the motion-value at the end of the motion (end of the Last Segment) change, and it becomes different to the motion-value at the start of the motion.

To Edit the Motion-Value at the Start of the First Segment

6.Click the Radio-Button that is above the 'Specify-Start'4s Control-Button - see image below
7.Edit the motion-values in the data box6s

When you edit the motion-value in the box, the motion-value at the start of the motion (start of the First Segment) changes, and it becomes different to the motion-value at the end of the motion.
