# Scan-to-CAD handoff checklist

Best3DScanner original blank worksheet · Updated August 30, 2026

Guide: https://best3dscanner.com/guides/scan-to-cad-workflow

This is a planning and recording aid, not a calibration certificate, inspection approval or measured example. Fill it with your own evidence. Blank means NOT CHECKED. Do not use a consumer scanner accuracy claim as an acceptance tolerance. Safety-critical work requires a qualified process.

## Job and output

- Part / revision:
- Intended use and mating part / drawing:
- Owner / operator / check date:
- Required output: reference mesh / printable mesh / editable CAD / other
- Receiving CAD application and version:
- Agreed exchange format:
- Native CAD file required: yes / no
- Unit system:
- Acceptance limits and who approved them:

## Capture and reference

- Scanner / optical mode / software version:
- Calibration record:
- Surface preparation and marker placement:
- Raw scan file(s):
- Clean reference mesh file:
- Untouched backup location:
- Independently checked reference dimension and method:
- Import unit confirmed:
- Missing or occluded geometry:
- Alignment datums / reference faces / axis convention:
- Repair, smoothing or reduction applied and why:

## Feature check record

Add rows for the features that control your actual fit. Example row names below are prompts, not measured results. Record the measurement method and its suitability separately; a numerical difference alone does not establish measurement confidence.

| Feature | Independent reference + units | Method / instrument | CAD value + units | Agreed limit | Pass / fail / not checked | Evidence file |
|---|---|---|---|---|---|---|
| Base thickness | | | | | NOT CHECKED | |
| Mounting hole diameter | | | | | NOT CHECKED | |
| Hole center spacing | | | | | NOT CHECKED | |
| Mounting-face orientation | | | | | NOT CHECKED | |
| Other mating feature | | | | | NOT CHECKED | |

## Reconstruction checks

- [ ] Primary references were established before secondary details
- [ ] Real openings remain distinct from unobserved data gaps
- [ ] Nominal dimensions and symmetry choices are documented
- [ ] Unobserved / inferred geometry is explicitly listed
- [ ] Editable dimensions update their intended dependent features in a test copy
- [ ] Deviation comparison includes its alignment convention, scale and limits
- [ ] Critical dimensions have independent checks, not only a color map
- [ ] Necessary prototype or fit-gauge test is recorded

## Export and handoff

- Native CAD file / revision:
- Exchange file / revision:
- Reference mesh file / revision:
- Check record / screenshots:
- [ ] Exchange file reopened in the receiving application
- [ ] Units and orientation confirmed after reopening
- [ ] Expected body type and body count confirmed
- [ ] Critical features checked after reopening
- [ ] Recipient has the native model if editable feature history is required
- [ ] Raw scan, cleaned mesh and CAD are retained as separate artifacts

## Decision

- Status: NOT CHECKED / REWORK REQUIRED / ACCEPTED FOR THE STATED USE
- Unresolved items:
- Evidence supporting the decision:
- Reviewer / date:

Checking every box does not independently validate the measurements. Approval remains tied to the stated use, acceptance criteria and evidence.
