Change Line Length Tool

What it Does

Makes a line longer or shorter. The line keeps its angle, and you choose which end moves.

Use this when a line needs to be a set amount longer or shorter, such as lengthening a side seam by 2 cm.

info

The blue point is the start of the line, and the green point is the end.

How to Use

1. Activate the tool by clicking the Change Line Length icon
2. Select the line to change, then select Continue
3. Enter the Change amount in the unit shown. A positive number lengthens the line and a negative number shortens it
4. Choose where the change happens: Change at Start Blue Point, Change at End Green Point or Change Equally at Both Ends. The first one is chosen to begin with
5. Select Preview to see the new line. The Length box shows the new length
6. To adjust, change the amount or the end and select Preview again
7. Select Save to keep the change, or Cancel to leave without changing the line

info

You can type a number or a formula for the change. See Entering Values. With Change Equally at Both Ends, half of the change is made at each end.

🧠Memorization

When you memorize a draft, the length change is remembered along with the amount and the end you chose.
