3D Scanning & CAD Reconstruction
Capture complex industrial geometry and convert scan evidence into usable engineering data. We support 3D scanning, mesh interpretation, CAD reconstruction, 2D manufacturing drawings, inspection references, and supplier-ready documentation for critical components.

Scan-to-CAD Workflow
Physical parts, meshes, and complex profiles can be digitized and converted into controlled CAD models.
Complex Geometry Capture
Cast surfaces, freeform profiles, housings, dies, fixtures, worn profiles, and mating interfaces can be captured with higher geometric confidence.
Manufacturing-Ready Output
Reconstructed CAD and drawings are prepared for vendor review, machining, fabrication, inspection, and repeat supply.
Why 3D Scanning & CAD Reconstruction
When complex geometry cannot be captured reliably by manual measurement alone
Many industrial components include cast surfaces, worn profiles, organic contours, tight packaging envelopes, or irregular interfaces that are difficult to document using conventional measurement alone. 3D scanning creates dense geometry evidence, while engineering CAD reconstruction turns that evidence into controlled data for manufacturing, inspection, and redevelopment.
Typical scan-to-CAD situations
These cases usually need both accurate capture and engineering interpretation before the component can be manufactured with confidence.
- Complex surfaces, castings, housings, impellers, dies, fixtures, or profiles are difficult to measure manually.
- A worn or failed part must be compared, corrected, and reconstructed against functional intent.
- Existing mesh, STL, or point-cloud data needs conversion into editable parametric CAD.
- Manufacturing vendors need drawings, datums, tolerances, and inspection references, not only raw scan files.
Scan-to-CAD Scope
From physical geometry to controlled CAD and production documentation
The work is structured to capture reliable geometry, reconstruct functional CAD, and create data that supports manufacturing, inspection, and future design control.
3D Scanning & Data Capture
- Capture of complex surfaces, profiles, cast features, tooling details, and hard-to-measure geometry
- Point cloud or mesh generation aligned to practical reference planes, datums, and feature zones
- Scan planning focused on critical interfaces, fitment areas, and functional surfaces
CAD Reconstruction
- Conversion of scan evidence into clean, editable CAD geometry
- Parametric reconstruction for bores, bosses, flanges, threads, mounting patterns, and controlled features
- Surface reconstruction where freeform, cast, contoured, or worn profiles must be interpreted
Drawing & Inspection Support
- Manufacturing drawings with critical dimensions, datums, fits, and tolerance notes
- Deviation review, comparison references, and checkpoints for supplier QC
- Documentation suitable for machining, fabrication, casting, tooling, and repeat procurement
Our Process
A controlled workflow from 3D scan evidence to engineering release
Requirement & Scan Strategy
We define component function, critical interfaces, measurement objectives, assembly constraints, and output requirements before scanning begins.
3D Scanning & Reference Capture
Visible geometry, critical zones, reference planes, mating features, and hard-to-measure profiles are captured using suitable scanning and measurement methods.
Mesh Processing & Geometry Review
Scan data is cleaned, aligned, segmented, and reviewed to separate usable geometry from noise, wear, damage, or irrelevant surface variation.
CAD Reconstruction
Editable CAD is built from scan evidence with practical feature logic, surface reconstruction, datum control, and manufacturing feasibility in mind.
Drawing & Inspection Package
2D drawings, critical dimension maps, tolerance notes, material inputs, finish guidance, and inspection references are prepared for vendors or internal teams.
Fitment & Release Support
Where required, reconstructed CAD and prototypes are checked against assembly interfaces, scan deviation data, and first-article inspection expectations.
Need a scanned part converted into CAD urgently?
Scan the QR to connect on priority. Send photos of the component, available mesh/STL/scan files if any, approximate size, application, critical faces, and deadline. Our team can quickly assess whether scan-to-CAD, drawing development, or manufacturing support is the right route.
- Share photos of the full part, critical surfaces, installed position, and mating components.
- Mention whether you have only the physical part, a mesh/STL, or old scan data.
- Approximate size, material, application, output requirement, and deadline are enough to begin.
- Suitable for maintenance, tooling, product engineering, purchase, and vendor development teams.

What You Receive
Scan-to-CAD outputs that support manufacturing and inspection
Every package is scoped around scan quality, geometry complexity, sample condition, functional criticality, manufacturing route, and inspection requirements.
Reconstructed 3D CAD Models
Clean, editable CAD models developed from scan evidence, measured references, and functional geometry interpretation.
2D Manufacturing Drawings
Datums, critical dimensions, fits, tolerance notes, material inputs, finish guidance, and revision-controlled documentation.
Mesh / Scan Reference Data
Organized scan evidence, mesh references, and geometry checkpoints for review, comparison, and traceability where required.
Deviation & Feature Notes
Practical notes identifying scan interpretation, worn zones, feature corrections, and manufacturing-critical surfaces.
Material & Finish Inputs
Material identification support, suggested equivalents, hardness guidance, coating notes, and wear-surface considerations.
Prototype & Release Roadmap
Clear next steps for prototype, fitment check, inspection, supplier quoting, procurement, and production release.
Have a scan file, complex sample, or difficult-to-measure part?
Send 3 inputs: full part photo, critical surface or failed zone close-up, and available scan/STL/mesh file if any. Add approximate size, application, required output, material if known, and deadline. We can review the likely scan-to-CAD route before a full form is filled.
Applications
3D scanning and CAD reconstruction applications
This service is suitable where complex geometry, worn parts, cast profiles, tooling details, or undocumented interfaces must be converted into usable engineering data.
Why Arrosa Engineering
Scan accuracy converted into manufacturing intelligence
Capture-to-function thinking
We prioritize scan areas that affect fitment, interface control, and component performance.
CAD built for editing
Reconstruction is developed as usable CAD, not a visually similar but difficult-to-manufacture model.
Inspection-aware output
Drawings and checkpoints help vendors and quality teams verify critical features with fewer assumptions.
Manufacturing coordination
Engineering data supports machining, fabrication, tooling, inspection, supplier quoting, and prototype review.

Frequently asked questions
Can you convert 3D scan data into editable CAD?
Yes. Scan, mesh, STL, or physical component data can be reconstructed into clean CAD. The final structure depends on geometry complexity, required manufacturing method, and whether parametric feature control is needed.
Do you provide only STL or also manufacturing drawings?
We can provide CAD models, 2D drawings, datums, critical dimensions, tolerance notes, material guidance, inspection references, and prototype or vendor support. Raw scan data alone is not the usual final deliverable for manufacturing.
What if the part is worn or damaged?
We review wear zones, symmetry, mating interfaces, functional surfaces, and operating requirements. Scan data is interpreted with engineering judgement so damaged geometry is not blindly copied into the CAD model.
Which components are suitable for 3D scanning?
Scanning is useful for castings, freeform parts, tooling, fixtures, gauges, housings, impellers, covers, brackets, formed parts, and any geometry that is difficult to measure manually.
Which details should I share first?
Send part photos, approximate dimensions, application, material if known, critical surfaces, required output format, available scan files if any, sample condition, quantity, and urgency.
