CNF Rear Geometry
Vicente Pattern CAD Specification
CAD-ready parameters for Levi's pattern engineers, derived from geometry targets and tension thresholds.
2. CAD Parameters
| Parameter | Value | Notes |
|---|---|---|
| Seat Ease | 14 mm ± 2 mm | Controls upper-seat tension |
| Thigh Ease | 10 mm ± 2 mm | Controls side-seam tension |
| Yoke Angle | 18° ± 2° | Controls rear curvature support |
| Rise Curve | mid + 0.03 curvature | Controls projection support |
| Rear Curve Support | 0.91 curvature ± 0.12 | Contour target |
| Projection Support | 27.5 mm ± 4 mm | Forward depth target |
3. CAD Layer Definitions
- Layer 1 — Body Reference Layer: SMPL-X body mesh, pelvic plane, projection vector.
- Layer 2 — Cloth Geometry Layer: jeans mesh, seam topology, curvature lines.
- Layer 3 — Pattern Layer: seat panel, yoke panel, thigh panel, waistband, rise curve.
- Layer 4 — Adjustment Layer: ease adjustments, curvature adjustments, yoke angle adjustments, rise curve adjustments.
