﻿ Tutorial 6: Edit the End of the LAST Segment [13.2]

# How to edit the End of the LAST segment?

## 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.

### Progressive

Definition: The position at the end of the Last Segment The position at the start of the first segment.

Do this:

 1 Click the left most Segment to make it the Selected-Segment.

The left-most Blend-Point is also the selected or 'active' Blend-Point.

 2 Start the Blend-Point Editor

Note: As always: the Blend-Point Editor edits the:

 • 'End of the Previous Segment' [when the left-most segment is the Selected-Segment, this is the end of the motion].
 • 'Start of the Selected-Segment [clearly, when the left-most segment is the Selected-Segment, this is the start of the motion].

The image below shows the default Position Controls in the Blend-Point Editor for the FIRST SEGMENT.

It is possible to edit the Positions at the End of the Previous-Segment AND the Start of the Selected-Segment.

We can give different values to these Positions;

Blend-Point-Editor - Postion Controls - Default First Segment

 3 Edit the Start and End Positions to be two different values.

In this case, i have changed the

 • End of the Previous-Segment to be -30mm [THE END OF THE MOTION]
 • Start of the Selected-Segment to be +30mm

In the Blend-Point Editor, below, you can see the two different Position values.

Blend-Point Editor: Differnt Positons - Progressive

### Non-Progressive

Definition: The position at the end of the Last Segment ≠ The position at the start of the first segment.

Usually, the Velocity and Acceleration at the start and end are also the equal.

Do this:

 1 Click the left most Segment to make it the Selected-Segment.

The left-most Blend-Point is also the selected or 'active' Blend-Point.

Blend-Point Editor: Differnt Positons - Non-Progressive
End of Motion = Start of Motion

 2 Start the Blend-Point Editor
 3 Click the Middle Control Button [the Match Control-Button] so it is as above.
 4 Edit the End Positions

Because the 'Match Control-Button is active, the Start is made to equal the End Position.
