We provide mechanical drafting and manufacturing drawing services for mechanical parts, welded structures and assemblies. Working from your approved 3D models or designs developed by our team, we prepare part, welding and assembly drawings with dimensions, tolerances, materials and bills of materials. We follow your agreed drawing templates, numbering system and workshop requirements. You can assign a complete drawing package, updates to existing drawings or recurring work when your team needs extra drafting capacity.
Mechanical drafting — scope and deliverables
What we produce
General arrangement (GA): overall sizes, interfaces, set-out datums, lifting/handling notes.
Assembly drawings: item balloons, BOMs, section/details, fit/clearance notes.
Detail drawings: part geometry, critical dims and fits, edge preps, notes for machining/welding/finishing.
Sheet-metal flats: flat patterns with bend tables (K-factor, radii, reliefs).
Profiles/plates: NC/DXF where applicable, cut lists, nesting remarks.
Erection/installation sheets: anchor positions, reference grids/levels, service clearances.
Methods & standards we apply
GD&T to ISO 1101; general tolerances to ISO 2768; weld symbols to ISO 2553; weld quality notes e.g. ISO 5817.
Hole/feature tables where efficient; thread and fit notation per ISO practice (e.g., H7/g6).
Consistent units, datums and view conventions; clear revision blocks and change notes.
Project requirements: we agree the applicable drawing standards and required information with your team. Certification is outside our drawing service.
Inputs we need
Final/approved 3D CAD or our model reference, accepted datum scheme and interfaces.
Your title-block/template and part numbering (or we provide ours).
House standards (fasteners, coatings, edge radii), shop capability limits and preferred file formats.
Quality checks before issue
Completeness: views/sections/details, BOM matches balloons, note stack coherent.
Manufacturability: tolerances vs process capability; no impossible stacks.
Assembly logic: clash-prone details called out; sensible fits and access.
Identification: item marks, weld sizes, materials and coatings unambiguous.
Before fabrication, the client reviews and approves the drawing package.
File formats & data
PDF for release; DWG/DXF for CAM/CNC; STEP references where needed; spreadsheets for cut lists/BOMs.
Transmittals with issue purpose (IFR/IFC/As-Built) and revision history.
Drawing support for your engineering team
We can work from your existing CAD models in the agreed software version or prepare drawings alongside our 3D CAD design services. Before starting, we confirm model completeness, drawing standards, required formats and review stages. For recurring assignments, we agree priorities and available capacity with your project lead.
Boundaries (so expectations match)
We do not stamp/certify, produce electrical schematics or full P&IDs/pressure-vessel code packages. However, we coordinate those interfaces and reflect them in the mechanical drawings where required.
Need a drawing package or extra drafting capacity? Send your model format, approximate number of parts and required delivery date. We will review the scope and confirm our availability.
Leave a Request
Tell us what needs to be drawn, which CAD software you use and when you need the drawings. We will confirm the scope, required inputs and availability before work starts.
