Professional CAD Design Services
SolidWorks, Fusion 360 & Production Files
We produce parametric, factory-ready 3D CAD models for mechanical parts, product assemblies, and industrial components. Every file is verified for dimensional accuracy and manufacturability before delivery. No intermediaries, no templates, direct engineering accountability.
Trusted by Global Engineering Teams & Product Companies
Our Core CAD Design & Modeling Services
Every engagement starts with your reference — a sketch, scan, PDF, or existing part — and ends with a verified, factory-ready 3D file.
SolidWorks 3D CAD Modeling
Parametric SolidWorks models with full feature tree, design intent, and correct constraints for CNC machining, injection molding, and additive manufacturing.
Fusion 360 Product Design
Consumer and industrial product design using Fusion 360 — including generative studies, simulation-ready geometry, and complete rendering assets.
2D Drawing to 3D CAD Conversion
Convert paper sketches, PDF blueprints, DXF layouts, and hand-drawn concepts into fully parametric 3D CAD models with tolerances and GD&T annotations.
Scan-to-CAD Reverse Engineering
From point clouds, CT scans, or physical parts — we reconstruct accurate parametric CAD geometry with full edit history for legacy part redesign and replacement manufacturing.
Assembly Modeling & BOM Documentation
Multi-component assembly design with exploded views, mate constraints, clearance verification, and complete Bill of Materials for manufacturing procurement.
DFM Analysis & Engineering Review
Pre-delivery DFM check validates wall thicknesses, draft angles, undercuts, and tolerance stacks against your target process — CNC, SLS, SLA, FDM, or injection molding.
Engineering Standard
Why Our CAD Files Are Production-Ready From Day One
Most CAD modeling agencies deliver visually correct files that fail at the factory gate — wrong wall thickness, missing draft, incorrect tolerancing. Our engineers work backwards from your manufacturing process, building every model to pass first-article inspection without revision cycles.
- All geometry modelled with defined design intent and parametric constraints
- Tolerance verified against target process (CNC, 3D printing, casting)
- Standard export formats: STEP, IGES, STL, DXF, PDF drawing
- Mutual NDA executed before any files or briefs are shared
- Revision scope confirmed in writing before work begins
Our CAD Modeling Process — From Brief to Delivered File
A structured five-step workflow removes guesswork and keeps every project on schedule.
Brief & Reference Review
You share your sketches, scans, PDFs, or physical part. We review your requirements, target manufacturing process, and tolerances before quoting.
NDA & Scope Confirmation
A signed mutual NDA is executed first. Scope, deliverables, file formats, and turnaround are confirmed in writing before any work begins.
Parametric Modeling
Engineers build the full 3D model in SolidWorks or Fusion 360 with correct feature tree, mates, and design intent — not surface shells.
DFM Check & Review
Every file is evaluated against your target process. Critical dimensions, draft angles, and wall thicknesses are confirmed before export.
File Delivery
You receive STEP, IGES, native format, STL, and a 2D engineering drawing — structured for immediate handoff to your factory or printer.
Solidus 3D vs. Generic CAD Marketplaces
What makes direct engineering engagement different from online freelancer platforms.
| Feature | Solidus 3D | Generic Marketplace |
|---|---|---|
| DFM Analysis Included | ✓ Every project | ✗ Rarely included |
| Signed NDA Before Sharing Files | ✓ Mandatory | ✗ Not guaranteed |
| Parametric Feature Tree | ✓ Full history-based model | — Varies by freelancer |
| Direct Engineer Communication | ✓ No intermediary | ✗ Platform moderated |
| Production File Formats | ✓ STEP, IGES, STL, DXF, PDF | — Often STL only |
| Quote Turnaround | ✓ Within 24 hours | — 24–72+ hours |
| Revision Scope in Writing | ✓ Confirmed before start | ✗ Often extra charges |
Track Record
Thousands of CAD Files Delivered Across 15 Countries
From hardware startups to industrial OEMs — our structured workflow scales to single parts or full product assemblies with equal precision.
What We Model — Sample CAD Project Categories
We work across mechanical, consumer, architectural, and medical device product categories. Every project type follows the same engineering discipline.
Mechanical & Industrial Component Design
Enclosures, brackets, flanges, housings, gearbox components, and precision machined parts. Full assembly with tolerances and engineering drawings.
Consumer & Commercial Product CAD
New product development from concept sketches — ergonomic forms, surface quality, fit and finish design, and complete BOM-ready assemblies.
Legacy Part Reconstruction & Scan-to-CAD
Obsolete parts, discontinued components, and physical objects converted to accurate parametric CAD models for re-manufacture or design improvement.
Architectural & Decorative 3D Modeling
Architectural visualization models, display showcases, trophy design, retail fixtures, and exhibit structures — ready for 3D print or CNC.
Frequently Asked Questions — CAD Design Services
Common questions from engineering managers, product developers, and procurement teams before starting a CAD project.
What CAD software does Solidus 3D use?
We work primarily in SolidWorks and Fusion 360. We also support CATIA and AutoCAD. All deliverables are exported in universal production formats: STEP, IGES, STL, DXF, and DWG — compatible with every major CAM, CAE, and PLM system.
How quickly can I receive a completed CAD model?
Quotes are provided within 24 hours of receiving your reference material. Standard single-part models are typically delivered within 24–72 hours. Complex assemblies may take 3–5 business days — always confirmed at quoting.
Will my CAD files be production-ready?
Yes. Every model undergoes a DFM (Design for Manufacturability) review. We validate tolerances, wall thicknesses, draft angles, and feature accessibility against your specific manufacturing process — CNC machining, SLS nylon, FDM, SLA resin, injection molding, or vacuum casting — before delivery.
Do you sign an NDA before starting CAD work?
Yes. A mutual Non-Disclosure Agreement is signed with every client before any project files, briefs, or technical requirements are shared. All team members are bound by internal confidentiality agreements. Read our full NDA policy →
Can you convert my 2D drawing into a 3D CAD model?
Yes. We convert paper sketches, PDF drawings, DXF layouts, AutoCAD files, and engineering blueprints into fully parametric 3D CAD models with proper feature constraints, design intent, and accurate dimensional relationships. The resulting model is fully editable for future revisions.
