What We Convert at CHAC United
We provide comprehensive Paper to CAD conversion services, transforming your legacy documents into precise, editable CAD drawings that align with today’s engineering, architectural, and fabrication standards. Here’s what we expertly convert:

Structural & Architectural Drawings
We convert hand-drawn or scanned structural layouts, general arrangements, architectural designs, and building schematics into detailed, to-scale CAD files suitable for revisions, construction, or BIM integration.

Mechanical, Electrical & Plumbing (MEP) Layouts
From ductwork and electrical wiring to plumbing and HVAC systems, we digitize complex MEP designs into clear, layered CAD drafts, ready for coordination and execution.

Floor Plans, Elevations, Cross Sections
Every component - including detailed room layouts, vertical sections, façade elevations, and intricate construction notes - is carefully drafted to match original scale and intent.

Fabrication Drawings, Shop Drawings
We accurately convert fabrication-ready documents, including part details and material annotations, ensuring seamless integration with CNC workflows or prefabrication processes.

Site Plans, Permit Sets
Topographic layouts, grading plans, and regulatory permit drawings are digitized with full clarity for approvals, project planning, and stakeholder collaboration.

Old Blueprints, Hand Sketches
