CAD to BIM Conversion
Arrival 3D helps architecture, engineering, and construction firms outgrow flat, static blueprints. We convert DWG, DXF, or PDF files into fully parametric Revit BIM models, handing your design team a single, coordinated asset that drives everything from early construction to long-term facility management.
CAD to BIM conversion takes your flat 2D views and completely reconstructs them as intelligent 3D objects, locking in true geometry, parametric links, and embedded asset data. Unlike a simple file export, this is a knowledge-intensive modeling process. While a line in AutoCAD only represents flat geometry, an intelligent Revit object understands its own materials, thickness, and spatial relationships, turning static paper trails into an interactive, data-rich model. We accept almost any input format to begin the digital rebuild:
Even if your source drawings are decades old or inconsistent, our team audits and corrects the geometry before modelling begins.
We are the only CAD to BIM conversion provider in the USA that also operates its own fleet of 3D laser scanners. That means if your drawings are incomplete, inaccurate, or simply don’t exist, we can scan the building and fill the gaps giving you a complete, verified BIM model when drawings alone aren’t enough.
Every CAD to BIM services engagement is handled by experienced Revit modelers who understand documentation standards across all disciplines and project types.
2D architectural DWG and PDF drawings converted into complete Revit architectural models. Walls, floors, roofs, ceilings, doors, windows, and stairs built to your title block, view template, and naming convention standards. Output supports SD, DD, and CD phase documentation.
Structural 2D drawings — framing plans, sections, and foundation layouts — converted into coordinated Revit structural models. Steel, concrete, and precast elements modeled at the required LOD with connection details and slab openings included.
Mechanical, electrical, plumbing, and fire protection 2D drawings converted into coordinated 3D MEP Revit models. Duct routing, pipe runs, conduit, and equipment placement modeled from CAD source data and ready for coordination and clash detection.
Existing building drawings — often incomplete, outdated, or held only as PDFs — converted into accurate 3D BIM models for use as the base model on renovation, extension, and retrofit projects. Field verification recommendations provided where source data accuracy is uncertain.
Direct DWG to Revit conversion for architectural, structural, and MEP disciplines. AutoCAD layer structure mapped to Revit categories and system families. Parametric intelligence, schedules, and annotation standards applied to match your BIM template precisely.
Scanned and vector PDF drawings converted into intelligent 3D Revit models. Dimensions verified during conversion, and any discrepancies or unclear details in the source PDF are flagged and resolved with your team before the model is finalized.
Our services convert your data into a unified and intelligent model created to simplify VDC Coordination.
Unified Cross-Discipline Coordination: A single coordinated Revit model is built for architects, structural engineers, and MEP teams to work from. Design errors are identified and resolved before construction even begins, eliminating version conflicts.
Greater Accuracy, Less Rework: All the errors that are identified in the model are resolved with minimal expense compared to expensive on-site rectifications. The manual inconsistencies of maintaining separate 2D drawings across all disciplines are eliminated by Revit’s parametric environment.
Streamlined Quantity Take-offs: We efficiently secure exact dimensions and material types for your 3D assets. We replace manual tracking and ensure that estimators get field-accurate data instantly.
Clarity for Non-Technical Stakeholders: A 3D BIM model provides a clear visual to investors and clients, giving them a clear understanding of the project. It also reduces the approval timelines of projects.
A Long-Term Operations Asset: A BIM model output is functional for long-term usage across the utilities. Critical data such as equipment schedules, manufacturer details, and maintenance records can be integrated directly into the base model. This makes it compatible with facility management operations from day one.
Our modelers turn uncoordinated drafts into intelligent architectural and structural frameworks. We reconstruct flat blueprints into smart Revit elements, mapping out everything from framing and foundations to heavy MEP layouts like HVAC paths, piping loops, and electrical conduits.
We scale our output from LOD 100 to LOD 500 to match your current construction phase, turning basic conceptual massing into an intelligent as-built twin mapped to your exact software workflow rules.
Every CAD file gets a manual review; our team flags data gaps, drawing conflicts, and geometry issues before a single element is modeled. LOD targets are set here. That agreement is what keeps the scope from shifting mid-project.
Every structural, architectural, and MEP element is built as a native Revit object. Standard families cover most geometry, where they don’t, custom components are modelled accordingly. Parametric behaviour stays intact either way.
Each object in the model gets assigned its own material specs, fire ratings, manufacturer details, and maintenance data. We work to the agreed LOD if the specification calls for geometry only; that is what we deliver. If it calls for full data, every object carries it.
Before delivery, every model goes through a full interference check and a drawing-by-drawing geometric review against the source files. The final output is formatted to your project standards and handed off in your required file format.
Working with legacy CAD drawings from previous projects or acquired buildings? We convert them into Revit models ready for renovation design, addition planning, or BIM-compliant permit submissions.
Win more bids and run tighter projects. A BIM model from existing drawings lets your team run clash detection before breaking ground, generate accurate takeoffs, and coordinate trades in a shared model environment.
Turn your paper or CAD record drawings into a living facility model you can actually use for space planning, maintenance tracking, and tenant management.
Need a base architectural model to overlay your mechanical, electrical, or plumbing systems? We deliver a clean, structured Revit base model your MEP team can work on immediately. Managing a portfolio of buildings with outdated CAD documentation
Native parametric BIM model built to your template, naming conventions, and agreed LOD. Open and work with it on day one no cleanup required.
IFC 2×3 or IFC 4 export for use in Archicad, Tekla, BIM 360, open BIM tools, and software-neutral project handovers.
Coordination and clash detection model ready for Navisworks Manage. Load immediately for multi-discipline clash review.
Plan, elevation, section, and detail sheets plotted directly from the Revit model to your title block format.
2D CAD drawings derived directly from the BIM model — replacing your original source drawings with model-accurate documentation.
Door schedule, window schedule, room data sheet, wall type legend, and material quantities — all extracted automatically from the model.
Full documentation of every modeling decision assumptions made, dimensions inferred, items flagged for field verification, and discrepancies found in source drawings.
Yes, this is one of the most common conversions we handle. We take your legacy 2D DWG, DXF, or DGN files and manually reconstruct them into data-rich, 3D Revit environments.
LOD tracks how dense your model’s geometry and embedded metadata actually are, scaling from LOD 100 conceptual lines to LOD 500 verified as-built twins. Arrival 3D matches your current construction phase to the correct LOD upfront, so your project team gets exactly what they need without wasted budget.
Single-discipline conversions are completed in three to five business days. Multi-discipline projects covering architecture, structural, and MEP typically take two to four weeks. Arrival 3D fixes your exact completion dates upfront at the quoting stage.
Choose between RVT, IFC, NWC, or 3D DWG file hand-offs. Our modelling team works entirely inside Autodesk Revit, utilising standardised IFC formats to ensure your final files open seamlessly inside any software platform your contractors run
Flat drawings miss critical structural data. Unlike a traditional CAD, which just drafts lines to represent a layout visually, a 3D Revit model embeds elements like fire ratings and material codes in the objects, thereby automating the clash detection and accurate material take-offs directly from the model.
