Description
Subtract garmentCenterCoordinate from pocketCenterCoordinate for centerOffset.
Garment and pattern calculations use measurements, allowances, fold conventions, and repeat positions. A local calculation is one pattern component; fabric behavior, fit, and manufacturing tolerances require separate assessment.
Subtract garmentCenterCoordinate from pocketCenterCoordinate for centerOffset.
When to use this tool
Use Pocket Placement Center Line Offset when you need a bounded pattern, spacing, or allowance component using consistent length units.
How to use the tool and how it works
- Enter garmentCenterCoordinate, pocketCenterCoordinate, pocketWidth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read centerOffset, innerEdgeCoordinate, outerEdgeCoordinate. Use the output convention below.
Subtract garmentCenterCoordinate from pocketCenterCoordinate for centerOffset. Return pocket center minus and plus half pocketWidth as edge coordinates.1

| pocketCenterCoordinate | Pocket Center Coordinate | Required. Finite number. |
| pocketWidth | Pocket Width | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| centerOffset | Center Offset | Required. Finite number. |
| innerEdgeCoordinate | Inner Edge Coordinate | Required. Finite number. |
| outerEdgeCoordinate | Outer Edge Coordinate | Required. Finite number. |

}Limitations and assumptions
- Inner and outer labels follow the chosen numeric axis, not automatically the garment's anatomical sides; no seam allowance, fit, or placement preference is inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check the complete pattern and test fit or material behavior before production.
