CAD Conversion to SolidWorks

Convert Files, Keep Design Intent

STEP, IGES, Parasolid, STL, PDF, DWG — if your team works in SolidWorks, neutral and legacy formats are a bottleneck. We convert them into native SolidWorks files with a real parametric feature tree, so you can edit, tolerance, and revise instead of working around an imported body.

Conversion quality is the difference between a "dumb solid" and a working model. We rebuild geometry with feature history, re-mate assemblies, and regenerate drawings — so the next design change doesn't cost you a full redo.

Core Capabilities

  • Neutral to Native: STEP, IGES, Parasolid, and X_T files converted to editable SolidWorks parts and assemblies.
  • 2D to 3D: PDF, DWG, and paper drawings rebuilt as parametric 3D models with correct proportions and dimensions.
  • Mesh to Solid: STL and OBJ data from scanning or printing converted to solid, manufacturable geometry.
  • Assembly Rebuild: Components re-mated, with interference checks and a clean BOM structure.
  • Drawing Regeneration: Fresh 2D drawings with dimensions and GD&T issued from the converted model.

Neutral File vs. Native SolidWorks

Why conversion matters — and what you gain when the model is rebuilt, not just imported.

Workflow Neutral file (STEP/IGES) Native SolidWorks (converted)
Editability Geometry only — changes require re-import or re-modeling Full parametric feature tree, dimensions you can modify
Design changes Each revision starts from scratch Edit a feature or dimension and the model updates
Drawings Regenerated manually from the imported body Update automatically with the model
Assemblies Mates and structure are lost Mates rebuilt and verified, BOM structured
FEA & CAM Extra prep steps, unstable geometry Clean solid models, ready for simulation and machining

When You Need CAD Conversion

These are the situations where a conversion project usually starts.

Supplier & Partner Files

A customer or vendor sends STEP or IGES and your team needs editable SolidWorks to make changes, add features, or run internal checks.

Legacy Designs

Old drawings or discontinued CAD formats that need to live in today's toolchain — without losing the original design intent.

Scan & Print Data

STL meshes from 3D scanning or printing that must become solid, manufacturable geometry for machining, molding, or simulation.

What You Receive

Every conversion project ends with files your team can actually work from.

Native SolidWorks Files

Parts and assemblies with rebuildable feature history and structured feature names.

Neutral Formats

STEP/IGES re-exports of the converted model for collaboration with any partner or system.

Drawings & Report

Updated 2D drawings with dimensions and GD&T, plus a conversion report listing rebuilt features and assumptions.

CAD Conversion FAQ

How long does a conversion take?

It depends on part complexity and source quality. We review the files first and quote a fixed price and deadline — typical parts convert within days, not weeks.

Can you convert 2D drawings to 3D?

Yes. PDF, DWG, or paper drawings can be rebuilt as parametric 3D models. Where dimensions or tolerances are missing, we flag them rather than guess.

What if my file has no feature history?

We rebuild it as native parametric features, so you get an editable model instead of a frozen imported body.

Get Editable CAD, Not a Dead File

Send your STEP, IGES, PDF, or STL — we will review it and quote the conversion before any work starts.
