Match a 30mm sphere within 1mm chamfer D · D1 · d1-sphere-01

Prompt

Reference images of a 30mm-diameter spherical bead are attached. Design a .vcad that reproduces this shape as closely as possible. The grader will compare your output's tessellated mesh against the target sphere via bidirectional Chamfer distance, in millimetres; a symmetric average of 1mm or less passes.

Requirements:
- Single solid, single-root .vcad.
- Centred on the origin (the target is centred at the origin).
- Aim for smooth surface (use ≥ 32 segments on curved primitives).
- The simplest correct answer is a 15mm-radius Sphere primitive at the origin.
