CAD Drafting Services
High-fidelity 2D drafting for manufacturing, fabrication and installation with ASME/ISO/BS compliance.
CAD Drafting — engineered for industrial performance.
CAD drafting services produce production-grade 2D drawings — GA, fabrication, assembly and installation — to ASME, ISO, BS and client standards. Our drafting teams work in AutoCAD, SolidWorks Drawings, MicroStation and DraftSight and deliver revision-controlled sets with full GD&T. For EPC, OEM and shipyard clients, outsourced CAD drafting means a scalable drawing office without hiring risk, and consistent quality across drawing packs measured in the tens of thousands.
Our engineers combine first-principles calculation with modern 3D CAD and simulation to deliver work that plugs directly into your fabrication, procurement and construction workflows. Whether you need a short burst of expert capacity or a long-running dedicated engineering pod, our cad drafting team is built to scale with your program.
