The Hem tool creates a hem allowance on your patterns. The program will measure the width of the item at the fold distance and adjust the final hem line/curve to match. If you have a pattern that flares out or in at the hemline, this tool will makes sure your hem is as wide as it needs to be when folded to the inside.

For this tool to work, you must have a line/curve drawn at the edge that will receive the hem. You also need lines/curves connected to this on both sides. In the images below the hem edge is the bottom of the pants and the sides are the inseam and outseam lines.

Select the line on the pattern edge that will receive the hem.

Next, select the side lines that are connected to the hem edge line.

Enter a value for the Hem Depth. This is how much of the fabric you will turn under to form the hem. You'll see there are two new reference points on the side lines/curves that indicate where the folded hem will rest.

If the hem appears on the wrong side of the hem edge line, select the Other Side button.

You also have the option to enter a value for the Raw Edge Turn. Another line will be drawn to turn under to enclose the raw edge before turning up the hem.

This is the final hem. Add any additional outlines needed before output.
