Input evidence
Mapped before scope
Brief, references, constraints and current files are mapped before scope is recommended.
File handoff
3D File Handoff Checklist
File handoff quality affects review speed. Useful 3D packages make assembly logic, dimensions, materials and unresolved risks visible.
Visual context
What this checklist should support
A checklist is useful only when it connects to project evidence that a buyer, engineer or supplier can review.
Structure evidence
Supplier-ready handoff
3D structure, assembly logic and exploded views make supplier handoff easier to review.
Prototype evidence
Prototype learning path
Sample route, fit checks and revision notes show what the next prototype should prove.
Production evidence
Pilot risk control
DFM notes, supplier questions and pilot gates reduce late surprises before tooling or launch.
Checklist
What this resource helps clarify
Use the table as a project-preparation checklist before sharing files or requesting a first development path.
| Area | What to prepare | Why it matters |
|---|---|---|
| Native files | Editable 3D files, drawings and configuration notes when available. | Preserves design intent for structure and assembly review. |
| Neutral files | STEP, STL, drawings, exploded views and reference screenshots. | Lets reviewers and suppliers inspect geometry quickly. |
| Context files | PCB outline, components, fasteners, sample photos and supplier comments. | Connects file geometry to real product constraints. |
Send for review
Turn the checklist into a next-step recommendation
A short product description is enough to start. Sensitive technical, supplier and prototype files can wait until NDA terms are agreed.
Prepare files for review
Send product type, current stage, target market and the context you can safely share now.
