Check how much the garment or fabric stretches under external stress as a percentage.
- Click and hold the
Fit Map icon, and select
Strain Map (Alt + 7).
→ Shows how much the garment is stretched as a percentage.
Adjust the settings in the Strain Map window.

Description
Global
Global Mode uses the same scale in the Strain Map, making it easy to see how much a pattern has stretched from its original shape, regardless of fabric type. Range
The Strain Map divides the range from the base 100% (no strain) to your defined maximum into 8 segments.
Blue: Indicates 100% stretch, meaning no strain or deformation.
Red: Indicates the defined maximum (e.g., 120%), representing the upper limit of stretch.
Gradation: Values between 100% and the maximum are linearly calculated and expressed as a smooth color gradient.
📝 Note: You can manually adjust the colors by clicking the each color chip.
Fabric
Fabric Mode uses each fabric’s stretch limit in the Strain Map, making it easier to see a more accurate and realistic fit.
Range
The Strain Map divides the range from 100% (no strain) to the fabric’s maximum stretch into 8 segments.
📝 Note: Each color chip can be selected to manually adjust the colors.
Stretch
The wearable stretch limit is automatically calculated and applied based on each fabric's physical properties.
The stretch limit is the point where the fabric can no longer stretch comfortably under a standard level of force, meaning the garment becomes too uncomfortable to wear.
For example, stiff fabrics reach this limit with minimal stretch, while flexible fabrics can stretch much more before reaching their capacity.
📝 Note: You can manually adjust the maximum stretch as needed.
Click a point on the simulated 3D garment to see detailed values at that location.
Dominant Direction
Indicates the specific direction (Warp, Weft, or Bias) that is closest to its stretch limit.
Actual Strectch
Shows the raw physical stretch percentage in the Dominant Direction.
Force
Calculates how close the fabric is to its maximum stretch capacity, where 100% represents the fabric's defined limit. Exceeding 100% means the fabric has been stretched beyond its defined capacity.
