Smarter Design Development Through Strategic Structural CAD Drawing Services

With over 29 years of experience in structural CAD drafting and engineering documentation, Optimar Precon delivers reliable and detailed Structural CAD Drawing Services for projects across the US, UK, Canada, and UAE.

Our team of experienced structural engineers, drafters, and CAD specialists uses advanced tools such as AutoCAD, Revit, and Tekla Structures to produce standards-compliant drawings from sketches, PDFs, or BIM models.

We help builders, contractors, and fabricators achieve precision in detailing, improve cross-disciplinary coordination, and ensure smooth execution from design to construction across steel, concrete, and hybrid structures.

Structural 2D Drafting

We create precise structural CAD drawings, including framing plans, foundation layouts, and reinforcement details. Each drawing follows accurate layering, annotation, and dimensioning for construction-ready documentation.

Structural 3D Drafting

Our structural drafting experts use Revit and Tekla Structures to produce intelligent 3D drafts that visualize connections, rebar, and member details. This enables clash-free coordination with architectural and MEP models.

Structural Steel Drawings

We deliver detailed structural steel drawings for fabrication and erection, including shop drawings, assembly details, and bolt schedules, ensuring precision in manufacturing and installation. 

Reinforcement and Concrete Detailing

Our structural drafting team provides bar bending schedules, reinforcement detailing, and concrete layouts with complete specifications, improving construction accuracy and reducing on-site ambiguity.

As-Built and Record Drawings

We update redline and field changes into accurate as-built structural CAD drawings, giving you complete documentation for project closeout, audits, or facility management.

CAD Conversion and Standardization

Convert legacy blueprints or PDFs into editable structural CAD drawings. We follow layer standards, symbology, and templates to ensure compatibility with your existing project documentation.
