When you are working with Garment Maker, you may encounter errors if your splines are set up incorrectly. This topic lists the common error messages you might see, and how to correct the problems they report.

Cannot remesh: the number of panels has changed: This error occurs when the user has modified the original pattern, and added new closed splines to it. The only way to correct this is to delete the original Garment Maker modifier and reapply a new one.

Number of boundary curves has changed: Users will get this error if they add or remove splines from the pattern after the initial application of Garment Maker. To correct it, delete the original Garment Maker modifier and reapply a new one.

Boundary splines do not form a closed loop: In this case, the splines that the user has tried to apply Garment Maker to don't form closed loops. Often, this is caused by an extra vertex and segment attached to one of the splines, and usually this segment is so small you cannot see it. It can be difficult to find the offending part. To remedy this situation, select all the vertices, weld them, then re-break them at the corners.

Splines form overlapping loops: When a user gets this error, it means that some panel loops overlap others (in the XY plane of the local view). If you create the shape in the Top view this should not happen (provided you don't create overlapping loops). Most commonly, this occurs when the user create the splines in a viewport other than Top and on a plane other than the XY plane.

Unable to create seam: This error happens in when trying to create a seam in two cases:

• One (or more) of the segments/MultiSegments in the attempted seam forms a closed loop (for example, if you make a MultiSegment from the armhole segments, that MultiSegment forms a closed loop if you create seams at the shoulder and below the armhole). You will have to delete one of the seams so that the MultiSegment is no longer closed. For an armhole, you generally keep the seam below the armhole open when you join it with the sleeve. You can then close the seam. For the same reason, the sleeve cannot be seamed at the underside before joining to the armhole.
• A MultiSegment in the attempted seam contains segments that are not contiguous and that are not linked by any seam.

Seam line topology is wrong: This error usually occurs when you try to make a closed loop into a seam. The loop might be natural, or it might be the result of seams created earlier.

For example, when creating a shirt, if you first create the sleeve seam along the length of the sleeve, and then attempt to sew the sleeve to the armhole, this message appears. This is because a loop has been created in the spline that defines the top of the sleeve. The solution in this example is to create the seams in the correct order:

1. Shoulder-front to shoulder-back
2. Sleeve to armhole
3. Side-front to side-back
4. Along the length of the sleeve
