Introduction

CAD drafting built for how Illinois projects actually move through review

A CAD drawing set for a Loop mixed-use tower is not the same job as one for a Grayslake data center shell or a Rockford manufacturing retrofit - different disciplines lead, different code amendments apply, and different reviewers are checking the set. Drafting that treats every project the same way costs time in RFIs and revision cycles that a discipline-matched drawing set avoids from the start.

Drafting Buddies has produced CAD drawing sets for architects, engineers, contractors and manufacturers across all 50 states for over a decade, with Illinois as a consistently active market - driven by Chicagoland's data center buildout, Stellantis' reopening of its Belvidere plant, and steady commercial, healthcare and institutional construction statewide. Every Illinois drafting engagement starts by confirming which code edition and local amendments apply to your project's jurisdiction, whether that's the home-rule Chicago Building Code or the statewide baseline now enforced under Public Act 103-0510.

Whether you need 2D architectural CAD drawings for a Naperville permit set, 3D mechanical CAD modeling for a manufacturing client, or a legacy paper drawing set digitized into clean, layered DWG files, our drafters work directly in AutoCAD, Revit, Civil 3D and SolidWorks - so files move straight from our desk into your existing project workflow without a format conversion step in between.

Illinois Building Code Landscape

Confirmed against the code cycle your Illinois jurisdiction actually enforces

Illinois moved from a state with no unified building code to a statewide baseline under Public Act 103-0510, requiring every municipality and county to enforce a code drawn from the 2018, 2021 or 2024 ICC family, with rolling compliance deadlines through 2025-2026. Home-rule cities keep their own amended codes layered on top of that floor.

  • Chicago Building Code

    Locally amended, enforced independently of the statewide baseline inside city limits.

  • Statewide baseline (PA 103-0510)

    2018 / 2021 / 2024 IBC, IRC & IEBC family, mandatory where no local code exists.

  • Illinois Accessibility Code (2018)

    Governs accessibility statewide, including on public-agency drawing sets referencing 2024 IBC.

  • Illinois Energy Conservation & Plumbing Codes

    Mandatory statewide regardless of local building code adoption.

Sub-Services

Illinois CAD design and drafting sub-services

Twelve discipline-specific CAD drafting and design services, color-mapped to the discipline they belong to and scoped to Illinois project and code-review requirements, plus Michigan coverage for teams working both sides of the state line.

ArchitecturalStructuralMEPCivilMechanicalConversion & Documentation

SVC 01

2D CAD Drafting Services

Flat, dimensioned 2D drawing sets covering plans, elevations, sections and details for architectural, structural and mechanical projects. Drawings follow consistent layer naming, line-weight and dimensioning standards so your team, contractor or permit reviewer can navigate the file instantly. Whether you need a full construction document set or a single detail sheet, drawings are built clean and ready for markup, bidding or permit submission across any Illinois jurisdiction.

SVC 02

3D CAD Design & Modeling

Solid and surface 3D CAD models for architectural massing, mechanical components and product design, built in SolidWorks, AutoCAD or Revit depending on the deliverable. Models are dimensionally accurate and structured for downstream use in rendering, fabrication or further engineering analysis, giving Illinois manufacturers, engineers and design teams a model that supports visualization and production rather than just a static image.

SVC 03

Architectural CAD Drafting

Floor plans, elevations, sections, permit sets and construction detail drawings for residential and commercial architecture, checked against the Illinois Accessibility Code and applicable local amendments. Drawings are coordinated with the architect of record's design intent and formatted for permit submission, keeping dimensions, hardware call-outs and finish schedules consistent from design development through construction documentation.

SVC 04

Structural CAD Drafting

Framing plans, foundation drawings, connection details and structural steel detailing produced in AutoCAD, coordinated against the structural engineer of record's design and the wind and seismic provisions governing your Illinois jurisdiction. Drawings support both design development and fabrication-ready shop drawing production, giving structural engineers and fabricators a consistent drawing base to build from.

SVC 05

MEP CAD Drafting

Mechanical, electrical and plumbing CAD drawings covering ductwork layouts, piping, conduit routing, panel schedules and fixture placement, coordinated across trades to flag conflicts before installation. Drawings are checked against the National Electrical Code and Illinois Plumbing Code, giving mechanical, electrical and plumbing subcontractors a coordinated set rather than conflicting single-trade drawings.

SVC 06

Civil CAD Drafting

Site plans, grading plans, utility layouts and drainage drawings for land development, subdivision and infrastructure projects, produced in Civil 3D and AutoCAD. Drawings account for stormwater and utility coordination requirements common to Illinois municipal review, giving civil engineers and site contractors a drawing set that moves cleanly through local plan review and permitting processes.

SVC 07

Construction CAD Documentation

Complete construction documentation sets combining architectural, structural and MEP drawings into a coordinated bid- and permit-ready package. Sheet indexing, title blocks and revision tracking are set up consistently across the full set, giving GCs, subcontractors and permit reviewers a documentation package that reads clearly from cover sheet through the last detail sheet.

SVC 08

As-Built CAD Drawings

Field-verified as-built drawings capturing actual constructed conditions for owner records, facility management and future renovation planning. Existing condition surveys, measured drawings and post-construction field changes are incorporated into a clean CAD record, giving Illinois owners and facility teams a reliable drawing set that reflects what was actually built rather than the original design.

SVC 09

CAD Conversion Services

Conversion of PDFs, scanned drawings, TIFF images and hand-marked sketches into clean, layered DWG or DXF files. Legacy paper drawing sets and outdated formats are digitized accurately, preserving dimensions and annotations while organizing content into standard CAD layers, giving Illinois firms a usable digital drawing archive instead of unsearchable scanned images or fragile original paper sets.

SVC 10

CAD to BIM Conversion

Existing 2D CAD drawing sets converted into coordinated 3D Revit models, useful for project teams transitioning from CAD-based to BIM-based delivery mid-project or preparing for future renovation phases. Model geometry is built to match the source drawings while adding the parametric structure needed for clash detection, scheduling and quantity takeoff later in the project.

SVC 11

Mechanical & Product CAD Design

Machine, equipment and product component drawings for manufacturers and machine shops, built in SolidWorks or AutoCAD with tolerances and material call-outs ready for CNC fabrication or production. Drawings support both prototyping and production runs, giving Illinois manufacturers a drafting partner for equipment design, retooling projects and ongoing product development work.

SVC 12

AutoCAD Shop Drawing Drafting

Fabrication-ready shop drawings produced in AutoCAD for structural steel, millwork, metal and MEP fabricators, detailed to trade-specific fabrication standards and coordinated against the project’s design documents. Piece marks, dimensions and connection details are drawn to match what your fabrication shop needs to cut, weld or assemble accurately the first time.

SVC 13
