Design Phase 1
Sketch | 3D Model | Render

Design Phase I

Sketch ideation and 3D modeling bring early product ideas to life for review, refinement, visualization, and direction.

Engineering Phase 2
3D Model | Orthographic Drawings

Engineering Phase II

Technical development, orthographic drawings, functional details, and documentation for manufacturable solutions.

Prototype Phase 3
Prototyping

Prototype Phase III

Prototype displays validate form, scale, durability, interaction, and production feasibility before full rollout.
