​3D Technical Pattern Maker for Modular Children's Underwear Line (2 Styles, 3 Front Panels)

​I need a technical designer to draft two Master Styles graded across a standard children's size range (Sizes 2T to 8). Each master style needs three interchangeable front-panel variations that utilize the exact same waistband, side-seam, and manufacturing assembly geometry. ​The Required Pattern Deliverables: ​Style 1: Boxer-Brief / Short Cut (Short leg extension) ​Variation A: Contour Pouch Front ​Variation B: Traditional Flat Front ​Variation C: Adaptive / Neutral Hybrid U-Gusset Front ​Style 2: Classic Brief Cut (High-cut leg opening) ​Variation A: Contour Pouch Front ​Variation B: Traditional Flat Front ​Variation C: Adaptive / Neutral Hybrid U-Gusset Front ​Technical Requirements & Formats: ​Material Spec: Patterns must be optimized for a Cotton Spandex Jersey knit with approximately 50% 4-way stretch and 95% recovery. ​2D Production Files: Production-ready 2D vector pattern blocks formatted in DXF/AAMA (for manufacturing) alongside layered, easy-to-print PDFs for initial home-sample sewing. ​3D Simulation Files: Companion 3D digital simulation project files (CLO3D .zprj or equivalent) demonstrating the drape, stretch fit map, and custom graphic pattern placement of all 6 variations on a child avatar. ​Commercial Rights: The final milestone payment includes a complete transfer of all intellectual property, design ownership, and full commercial rights for production, marketing, and retail use. ​Please share examples of children’s apparel, knitwear, or undergarments you have digitally drafted or graded. Thank you!
