CORE
SERVICES

From concept sketches to full production-ready files — we handle every stage of the design lifecycle with uncompromising precision.

01
3D Solid Modeling

Parametric and direct 3D models built in SolidWorks, Fusion 360, CATIA, and Creo — optimized for manufacturing, assembly, and simulation.

02
Technical Drafting

Precise 2D drawings with GD&T annotations, section views, and full BOM — compliant with ASME Y14.5 and ISO 128 standards.

03
28.00
Mechanical Design

End-to-end product design from ideation through DFM — gears, frames, enclosures, fixtures, tooling, and complex assemblies.

04
Structural Analysis

FEA simulation and stress analysis using ANSYS and SolidWorks Simulation — validate designs before material and manufacturing investment.

05
Sheet Metal Design

Flat-pattern development, bend allowance calculations, and production-ready DXF exports for laser cutting, stamping, and forming operations.

06
Reverse Engineering

Scan-to-CAD workflows using point cloud data and physical measurements — recreate legacy components with modern tolerances and documentation.

Years of Precision

PRECISION IS OUR STANDARD

Founded by lead designer Marcus Oyelaran, 20 Miline was built on one conviction: that great engineering design should be obsessively accurate, beautifully documented, and delivered on time — every time.

We've spent over a decade serving manufacturers, product startups, construction firms, and R&D labs across four continents. Our team brings deep expertise across AutoCAD, SolidWorks, CATIA, and Rhino, with a rigorous QA process that treats every tolerance as critical.

  • ISO-compliant technical drawings with full GD&T annotation
  • Dedicated project manager and direct designer access
  • Certified professionals across SolidWorks, CATIA, Fusion 360
  • 48-hour turnaround on standard drafting requests
  • Strict NDA and IP protection on every engagement
Work With Us

OUR DESIGN
PROCESS

01
Brief & Scope

You share your requirements, sketches, or reference files. We define deliverables, formats, and a clear timeline — before any work begins.

02
Concept & Draft

Our CAD engineers build initial geometry. You receive a preview draft within 24–48 hours for early-stage review and feedback.

03
Refine & Validate

We iterate on your feedback, run interference checks and tolerance studies, and ensure the design meets all manufacturing constraints.

04
Deliver & Support

Final files delivered in your required formats (STEP, IGES, DXF, PDF). We provide 30-day post-delivery support at no extra charge.

WHAT CLIENTS
SAY

The 3D models 20 Miline delivered went straight to our CNC machines without a single revision. That level of accuracy is rare — it saved us two full weeks of back-and-forth.

James Harrington
VP Engineering · Nexford Manufacturing

Working with 20 Miline feels like having a senior CAD engineer embedded in our team. Their responsiveness and attention to our design intent has been outstanding across every project.

Amira Khalid
Product Director · Solven Energy

They handled our most complex assembly — 400+ components — and delivered a complete, fully-constrained model in under two weeks. Exceptional skill and professionalism.
