The Fit Garment Analysis tool is accessible through the 3D Tool menu in the 3D window, providing greater fit insight for pattern makers.
Using the Fit Garment Analysis tool, you can identify different fit issues during the development process; for example, pieces deformation and overstretching (measured by FTU). You can also correct the pattern according to the Fit Analysis result.
Note the following:
The stretch warp and weft maps indicate on a piece by piece basis how it is stretched in 3D on a simulated garment, as compared with its original 2D size and fabric properties of the piece’s fabric.
The bar on the right side of the map shows values of the currently selected point (the slice appears according to the active map and baseline direction of the selected piece) on the piece, based on the used fabric. The bottom of the bar corresponds to the original (2D) non-stretched size (always 100%).
The deformation threshold that is always displayed at the ¾ of the bar shows the measured tear/deformation limit of the fabric.
Everything above the deformation threshold is overstretched and is clearly marked in orange-red on the garment. The stretch map also indicates how the pattern needs to be changed in order to relieve the stretch. Under the bar we show the 2D length along the warp/weft line on this piece, and the 3D length along this line on a simulated garment. If overstretch is detected, its size is defined below. This is a suggested 2D pattern correction. Below is an example of a correctly fit pattern: with the same size avatar and pattern.
Stretch Weft (Y): Provides the stretch and the overstretch data of the simulated garment in the Y direction perpendicular to the 2D baseline direction of each piece.
Stretch Warp (X): Provides the stretch and the overstretch data of the simulated garment in the X direction identical to the 2D baseline direction of each piece.
The following is an example of an overstretched pattern: a small sized pattern on a medium sized avatar. Note the red areas and 2D-3D differences under the bar, as well as the suggested overstitch amount.
DiThe distance map defines the distance between the simulated garment and the closest avatar points.
