2. CAD Development: From Concept to Digital Reality

Computer-Aided Design (CAD) and 3D prototyping have revolutionized the way custom jewelry is created. JINGYING specializes in transforming clients' jewelry ideas into precise CAD models and 3D-printed prototypes, bridging the gap between imagination and tangible reality .

2.1 Design Input Methodologies

JINGYING's CAD development process begins with understanding that inspiration manifests in many forms. The company has structured its design input process to accommodate various client inputs:

Photographs and Images: Clients may provide photographs of existing jewelry, natural objects, architectural details, or any visual inspiration. JINGYING's designers analyze these images to identify key lines, textures, and focal points, creating interpretive sketches that capture the essence of the inspiration in wearable form .

Hand-Drawn Sketches: Whether rough doodles or detailed technical drawings, sketches provide direct insight into the client's vision. JINGYING's CAD engineers translate these two-dimensional representations into three-dimensional digital models, adding necessary structural elements like internal galleries for stone settings, appropriate wall thickness, and ergonomic considerations .

Digital Files: For clients with advanced design capabilities, provided files in formats such as .STL, .OBJ, or .Rhino represent the most streamlined path to production. JINGYING conducts comprehensive Digital Design for Manufacturing (DFM) analysis, checking for non-manifold edges, wall thickness issues, undercuts, and stone setting compatibility .

Design Briefs: For clients beginning without visual materials, JINGYING guides them through creation of comprehensive design briefs including mood boards, target audience definitions, competitive analysis, and key descriptive terms that define the design ethos .

2.2 CAD Modeling Technologies and Software

JINGYING employs industry-leading CAD software to create precise digital models:
