We turn concepts, sketches, and requirements into production-ready CAD files — precise enough for CNC machining, 3D printing, fabrication, and manufacturing on the first pass.
Every service we offer ends with files you can send directly to a manufacturer, fabricator, or 3D printer — no guesswork, no back-and-forth. Projects typically start from $150, with custom quotes provided within 24 hours.
We build fully parametric 3D models — parts, assemblies, and sub-systems — using SolidWorks, Fusion 360, CATIA, and Creo. Whether you need a single custom component or a 100-part assembly, models are dimensionally accurate and built for real-world manufacturing. Used by product startups, inventors, R&D teams, and manufacturers preparing for production.
Precise 2D engineering drawings with full GD&T annotations, section views, detail views, and a complete bill of materials. Compliant with ASME Y14.5 and ISO 128 standards. We also convert legacy drawings, hand sketches, or rough PDFs into clean, production-ready CAD drawings. Used by manufacturers, procurement teams, and engineering firms.
Full product design from early concept through design-for-manufacturing (DFM) review. We design gears, enclosures, brackets, jigs, fixtures, and complex multi-component assemblies — with interference checks and manufacturability built into every step. Ideal for product companies, hardware startups, and engineering firms that need a complete design, not just a model.
FEA (finite element analysis) and stress simulation using ANSYS and SolidWorks Simulation. We identify failure points, optimize wall thicknesses, and validate load-bearing capacity before you spend money on material or tooling. Common use cases include structural frames, load-bearing brackets, mechanical housings, and any component where safety or durability is critical.
Flat-pattern development with accurate bend allowances, relief cuts, and k-factor calculations — ready for laser cutting, stamping, or press-brake forming. We design enclosures, chassis, brackets, and panels for electronics, industrial equipment, and architectural applications. Every file is export-ready for direct use on your cutting machine or at your fabrication supplier.
We recreate existing parts — whether broken, obsolete, or undocumented — as precise CAD models using physical measurements, photos, or 3D scan data (point clouds). The result is a fully dimensioned model with updated tolerances and complete technical documentation. Widely used for spare parts, legacy equipment, mold tooling, and component upgrades.
20 Miline was founded on a single principle: every drawing we deliver should be ready to manufacture. Not "almost ready." Not "needs one revision." Ready on the first pass.
Over the past 12 years, we've worked with manufacturers, hardware startups, construction firms, and R&D labs across four continents — from single-part prototypes to full product assemblies. Our team works in SolidWorks, AutoCAD, Fusion 360, CATIA, and Rhino. Every file goes through a structured QA process before it leaves our hands.
We handle work for product designers, engineers, inventors, and businesses of all sizes. If you can describe it or sketch it, we can build it.
Here's exactly what happens after you reach out — no ambiguity, no surprises. Most projects move from brief to delivery in 3–7 business days.
Share what you have — a sketch, a reference image, a rough PDF, or just a written description. We'll review it and send back a clear scope, fixed price, and delivery timeline within 24 hours. No commitment required at this stage.
Your assigned CAD engineer starts building. You receive a preview draft within 24–48 hours — enough to confirm direction, spot any misunderstandings early, and request changes before we go deep into detail.
We incorporate your feedback and run a full technical check: interference analysis, tolerance review, and DFM assessment. Every design is validated against real manufacturing constraints before we call it complete. Up to two revision rounds are included as standard.
You receive all files in the formats you need — STEP, IGES, DXF, STL, DWG, PDF — organized and clearly named. We include a delivery checklist confirming every file is present and accounted for. 30-day post-delivery support is included at no extra cost.

The 3D models 20 Miline delivered went straight to our CNC machines without a single revision. That level of accuracy is rare — and it saved us a full two weeks of rework and back-and-forth with our supplier.
Working with 20 Miline feels like having a senior CAD engineer embedded in our team. They pick up design intent quickly, communicate clearly, and consistently deliver files that are ready to use — not just ready to review.
We handed them a 400-component assembly with tight tolerances and an aggressive deadline. They delivered a complete, fully-constrained model in under two weeks — with zero interference issues. Exceptional work.
