Curve Truing Tool

What it Does​

Lets you check that two curves that sew together make one smooth curve. Truing means smoothing a join. Use this for seams such as an armhole that meets at a shoulder or side seam, or for one curve that is mirrored, such as a neckline.

The tool makes a temporary copy of the curves and their seam lines, and joins them end to end in the workspace. You move the curve points on your pattern, select Update, and watch the copy change. When the join looks smooth, you save.

To learn more about joining curves smoothly, see Drafting Dilemmas in the Academy.

  7. Select Continue
  8. Select the seam line that is connected to the second curve. To mirror one curve, select the same seam line again

If a curve and its seam line do not share an end point, a message asks you to select a different seam line.

Saving moves the curve points on your pattern for good. Check the preview before you select Save.
