Mechanical CAD Design and Manufacturing Drawings

 

What we do

We deliver production-ready mechanical CAD data — clean parametric models, robust assemblies, and professional drawings with geometric dimensioning and tolerancing (GD&T to ISO/DIN/ASME). Every package includes a supplier-friendly “Build Pack” so parts can be quoted and manufactured without back-and-forth questions.

The outcomes we aim for

  • DFM/DFA considered from the start (injection molding, machining, sheet metal)

  • Fewer fit issues through tolerance stacks and clearly defined reference surfaces/datums

  • Fast changes thanks to cleanly structured feature trees and configurations

  • Complete drawing and bill-of-materials packages that suppliers actually use

Services

  • Concept → CAD — packaging space, mechanisms, variants, fast 3D for decision-making

  • Parametric parts & assemblies — plastic, sheet metal, machined parts, cast and welded structures

  • Drawings & GD&T — ISO 1101 / ASME Y14.5, surface callouts, weld symbols (DIN EN ISO 2553)

  • DFM/DFA reviews — demolding/draft, wall thicknesses, stiffening ribs, tool accessibility, realistic CNC machining

  • Tolerance analysis — worst-case/RSS, 1D/2D tolerance stacks, functional gauges & inspection plans

  • ECAD–MCAD — PCB STEP/IDF, keep-out zones, connector accessibility, sealing/EMI, cooling paths

  • Reverse engineering — scan/mesh → NURBS/feature-based CAD; reconstruction of legacy data

  • Design automation — templates, design tables, macros/configurators

  • PDM/PLM setup — part numbering systems, revisions, title blocks, release workflows

  • Visualization — renderings, exploded views, technical illustrations

What you get from us (deliverables)

  • Native CAD data (SolidWorks/NX/Creo/CATIA/Inventor/Onshape) plus neutral formats STEP/Parasolid/IGES

  • Drawing package (PDF + DWG/DXF) with GD&T, surface callouts, and notes (bilingual DE/EN on request)

  • BOM & assembly data — item numbers, materials, fasteners, supplier part numbers

  • Manufacturing data — flat patterns, bend tables, draft checks, notes for tooling and mold making

  • Change documentation — revisions (ECN/ECR) and notes on model structure/feature-tree hygiene

  • Handover session — 45–90-minute walkthrough with your team

Technical stack

  • CAD: SolidWorks, Siemens NX, PTC Creo, CATIA V5, Inventor, Fusion 360, Onshape

  • Materials: Al/steel/Mg/Ti, ABS/PC/PA/PP/POM, elastomers/foams, composites

  • Standards: ISO 1101/2768/5459, DIN, VDA; ASME Y14.5 on request

  • Data formats: STEP, Parasolid, IGES, STL/OBJ (for reverse engineering), CSV/JSON for BOM/PDM

How a project runs

  • Discovery (~30 minutes) — requirements, manufacturing route, timeline

  • Design plan — risk list, tolerance strategy, file conventions, milestones

  • Modeling & drawings — iterative CAD with weekly updates and DFM checkpoints

  • Validation — interference checks, tolerance stacks, light FEA checks where useful

  • Release — drawing/BOM package, defined initial revision, handover to suppliers

What we need from you

  • Sketches/reference CAD, packaging space and interfaces, planned manufacturing processes/suppliers

  • Material specifications, surface/branding requirements (logos, marking zones, IP protection classes)

  • Company standards for title blocks, part numbers, revision logic

  • Success criteria (cost, lead time, weight, stiffness, IP rating, etc.)

Packages

  • CAD Starter — up to 20 parts, drawings & BOM, DFM review

  • Pro Build Pack — up to 100 parts, tolerance stacks, supplier handover

  • Automation & PDM — templates, macros/configurations, numbering system & release workflow

Practical examples

  • Electronics enclosure — rework of snap-fits, optimization of draft angles and ribs, IP-capable sealing concepts

  • Sheet metal chassis — flat patterns, hems/flanges, PEM hardware/rivet nuts, fastening concept

  • Milled bracket — weight reduction via pockets plus tool-friendly radii

  • Assembly standardization — fastener library & BOM cleanup for purchasing

Data security & compliance

By default we work under NDA, with version-controlled data storage and optional EU-only data hosting. On request, we can mirror your existing PDM/PLM system (e.g., SolidWorks PDM, Teamcenter, Windchill).

FAQ

Will we get fully editable models?
Yes — with clean feature trees, meaningful sketch names, and no broken references.

Metric or imperial?
Both. For customers in Germany we default to SI units (DIN/ISO).

Can you follow our drawing layout?
Yes. Send us your title block, preferred fonts, and layer structure — we will reproduce the layout exactly.

Is light FEA included?
Where it reduces geometry risk, yes — otherwise we can coordinate a full FEA as an add-on service if needed.

Can you work with our PCB team?
Yes — we support STEP/IDF workflows and define keep-out zones as well as service and connector clearance areas.
