Offset Curve Tool

What it Does​

Makes a copy of a curve that runs alongside the original at a distance you choose. Use this when you need a parallel curve, such as a seam allowance or the inner edge of a facing.

The copy is a new item, and the original stays where it is. The copy is a polyline (a line made of short straight segments), so it follows the shape of the curve but has no curve points you can move.

The tool works the same way as the Offset Line Tool. For help choosing seam allowance widths, see Seam Allowances in the Academy.

How to Use​

  1. Activate the tool by clicking the Offset Curve icon
  2. Select the curve to offset, then select Continue
  3. Enter the Distance, in the unit shown
  4. Select Preview to see the copy
  5. If the copy is on the wrong side, select Other Side
  6. Enter a name in the Name box
  7. Choose a color in the Style box
  8. Select Save to keep the copy, or Cancel to leave without adding it
info

The distance must be greater than 0. If it is 0 or empty, a message asks you to enter a distance and nothing is drawn. You can type a number or a formula. See Entering Values.

🧠Memorization

When you memorize a draft, the offset is remembered along with the distance you entered and the side you chose.
