Mechanical CAD Design & Drawings

What we do

We deliver manufacturing-ready mechanical CAD—clean parametric models, robust assemblies, and professional engineering drawings with GD&T (ISO/DIN/ASME). Every package ships with a supplier-friendly build pack so parts can be quoted and made without guesswork. 

Outcomes we target

  • DFM/DFA baked in from day one (molded, machined, sheet metal)
  • Fewer fit issues via tolerance stack-ups and clear datums
  • Fast changes through clean feature trees & configurations
  • Complete drawing/BOM packs suppliers actually use

Services

  • Concept → CAD – space claim, mechanisms, variants, quick 3D for decisions
  • Parametric Parts & Assemblies – plastics, sheet metal, machined, cast, welded
  • Engineering Drawings & GD&T – ISO 1101 / ASME Y14.5, surface finishes, weld symbols (DIN EN ISO 2553)
  • DFM/DFA Reviews – draft/wall checks, ribbing, tooling access, bend radii, CNC toolpath realism
  • Tolerance Analysis – worst-case/RSS, 1D/2D stacks, functional gauges & inspection plans
  • ECAD–MCAD – PCB STEP/IDF, keep-outs, connector access, gaskets/EMI, cooling paths
  • Reverse Engineering – scan/mesh → NURBS/feature CAD; legacy redraws
  • Design Automation – templates, design tables, macros/configurators
  • PDM/PLM Setup – part numbering, revisions, title blocks, release workflow
  • Visualization – renderings, exploded views, tech illustrations

Deliverables you receive

  • Native CAD (SolidWorks/NX/Creo/CATIA/Inventor/Onshape) + neutral STEP/Parasolid/IGES
  • Drawing Pack (PDF + DWG/DXF) with GD&T, finishes, notes (EN/DE on request)
  • BOM & Assembly Data – item numbers, materials, fasteners, supplier P/Ns
  • Manufacturing Data – flat patterns, bend tables, draft checks, molding notes
  • Change Log – revisions (ECN/ECR) and model tree hygiene notes
  • Handover Session – 45–90 min 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: STEP, Parasolid, IGES, STL/OBJ (reverse), CSV/JSON for BOM/PDM

How an engagement works

  1. Discovery (30 min) – requirements, manufacturing route, timeline
  2. Design Plan – risk list, tolerancing strategy, file conventions, milestones
  3. Model & Draft – iterative CAD with weekly drops and DFM checkpoints
  4. Validate – interference checks, tolerance stacks, light FEA where useful
  5. Release – drawing/BOM pack, revision baseline, supplier handoff

What we need from you

  • Sketches/reference CAD, envelope & interfaces, target processes/suppliers
  • Material preferences, finish/brand rules (logos, label zones, IP ratings)
  • Company standards for title blocks, part numbers, revisions
  • 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 handoff
  • Automation & PDM – templates, macros/configs, numbering & release workflow
    (Positioning tip: say “transparent, cost-effective pricing” or offer a clear price-match policy rather than “cheapest”.)

Example use cases

  • Electronics enclosure – snap-fit redesign, draft/rib optimization, IP-ready seals
  • Sheet-metal chassis – flat patterns, hemming, PEM/nutserts, fastener strategy
  • Machined bracket – weight reduction via pocketing + tool-friendly fillets
  • Assembly standardization – fastener library & BOM cleanup for procurement

Data security & compliance

Non-Disclosure Agreement (NDA) by default, version-controlled storage, and optional EU-based hosting. We can mirror your PDM/PLM (SolidWorks PDM/Teamcenter/Windchill).

FAQ

Will we get fully editable models?
Yes—clean feature trees, named sketches, and no broken references.

Metric or imperial?
Both. We default to SI (DIN/ISO) for Germany.

Can you match our drawing template?
Send your title block/fonts/layers; we’ll match them exactly.

Do you include light FEA?
Where it de-risks geometry, yes—or we coordinate full FEA as an add-on.

Can you interface with our PCB team?
Yes— STEP/IDF workflows, keep-outs, connector/service clearances.
