What Digital Reconstruction Actually Requires
And Why Mesh Conversion Isn't Enough

Mesh (.STL / .OBJ)

Triangulated Polygon Mesh Data
  • Polygon data only
  • Non-editable geometry
  • Inspection reference only
  • No feature history

Parametric CAD (.STEP / .IGES)

Clean Parametric CAD Feature History Tree
  • Editable feature tree
  • CAM / CNC ready
  • FEA / Simulation ready
  • 2D Drawing ready

What is Digital Reconstruction Services for Manufacturing?

Digital Reconstruction is the recovery of lost engineering knowledge from physical assets, converting 3D scan meshes and point clouds into editable parametric CAD models and production or tooling documentation for parts that have no surviving digital record.

When to Select This Service

Choose digital reconstruction when production or tooling documentation has been lost, when legacy manufacturing parts need to be rebuilt into usable CAD, or when a mesh-to-CAD conversion is needed to restore an editable design record.

FAQ

Frequently Asked Questions

What is the difference between raw scan data (STL) and a reverse engineered CAD model?

An STL mesh is a dead surface composed of millions of triangles that cannot be easily edited, dimensioned, or machined. A reverse engineered CAD model is a parametric solid (STEP/SolidWorks) with editable sketches, holes, fillets, and planes ready for manufacturing.

How do you handle worn or damaged areas on physical parts?

Our engineers analyze design symmetry, geometric primitives, and nominal fit interfaces to reconstruct the part to its original as-designed condition, eliminating physical wear and damage.

Can you reverse engineer internal features that cannot be scanned optically?

Yes. For complex internal channels and hollow castings, we combine optical scanning with physical silicone casting sectioning or Industrial CT scanning to capture internal wall profiles.

Do the reverse engineered models come with native feature trees?

Yes. Upon request, we provide fully parametric native models in SolidWorks, Siemens NX, Creo, or CATIA with logical feature trees, planes, and editable sketches.

How is accuracy validated before delivery?

We run a 3D deviation inspection comparing the reconstructed CAD solid directly against the original 3D scan point cloud, providing a certified 3D deviation report with every delivery.

Need to Digitize and Reconstruct Obsolete Components?

Tell us your component type, reconstruction goal, and required output format. We will deliver a highly accurate digital record for modern manufacturing.
