What Are CAD Services?
CAD Services involve creating, converting, revising, and managing digital construction drawings with computer-aided design software. These drawings help project teams document design intent, coordinate disciplines, support approvals, and prepare construction-ready information.
CAD services include 2D CAD drafting, 3D CAD modeling, CAD conversion, architectural CAD drawings, structural CAD drawings, MEP CAD drawings, shop drawings, fabrication drawings, redline updates, and as-built documentation.
In simple terms: CAD Services turn sketches, PDFs, markups, scans, and project information into accurate digital drawings that teams can review, edit, coordinate, issue, and use during construction.
