How to Import Revit Files into AutoCAD (Convert RVT to DWG Efficiently)

AutoCAD does not support native .RVT files for editing. If you need to work with a Revit model in AutoCAD, the standard approach is to export the model to DWG format and use it as CAD geometry.

There is also a second workflow used in coordination: attaching the RVT file as a reference model (read-only). Both methods are covered below.

This is a typical BIM to CAD workflow used in production across architecture and engineering teams.

Can AutoCAD Open Revit Files Directly?

AutoCAD cannot open or edit a .RVT file.

However, since AutoCAD 2017/2018, you can attach a Revit file as a Coordination Model:

• The RVT is loaded using the Navisworks engine
• It behaves like a read-only underlay
• You cannot modify geometry or access BIM parameters

This is useful for visual coordination, not for drafting.

Quick Method Selection (What Should You Use?)

Best Method to Convert Revit to AutoCAD (DWG Export)

1. Export from Revit (Standard Production Method)

To import a Revit model into AutoCAD, the most reliable method is to export views to DWG.

This converts BIM objects into lines, hatches, and blocks.

Steps:

• Open the desired view Use a 2D view (plan, section, elevation) or a controlled 3D view
• Launch export Go to: File > Export > CAD Formats > DWG
• Configure export settings (this is where most production issues happen)

Click “…” (Modify Export Setup):

Layers

• Map Revit categories to:
  • AIA
  • ISO
  • or your internal CAD standard

Bad layer mapping is one of the main causes of unusable DWGs.

Units and Coordinates

• Match units with your AutoCAD template
• Use correct shared coordinates if needed

This avoids scaling and alignment problems.

General Settings

• Select correct DWG version
  • AutoCAD 2018 format (used for 2018–2026 versions)
  • Avoid exporting to very old formats (e.g., 2000) → may degrade complex objects
• Control Xrefs behavior:
  • Linked (Xrefs) → lighter, modular workflow
  • Bound (Bind) → everything merged into one file

This is the “Bound vs Linked” decision:

• Linked = better for coordination
• Bound = better for file delivery

• Save the file Click Next, name the DWG, export

2. Importing the DWG into AutoCAD

Option A — Direct Open

Use OPEN command:

• Best for editing geometry
• File behaves as native AutoCAD drawing

Option B — External Reference (Xref)

Use ATTACH command:

• Keeps file lightweight
• Ideal for coordination workflows
• Allows updates without rework

3. Alternative: Coordination Model (Attach RVT Directly)

Instead of converting, you can attach the RVT:

• Use Coordination Model feature
• Works like a 3D reference
• No editing possible

Use this when:

• You need visual context only
• You want to avoid heavy DWG exports

Expert Tips for Clean DWG Output

Use a Section Box Before Export

• Export only what is needed
• Reduces file size
• Improves AutoCAD performance

This is one of the most effective optimizations.

Use Shared Coordinates

• Required for multi-discipline workflows
• Prevents alignment issues between Revit and AutoCAD

Simplify Hatch Patterns

• Complex hatches create heavy DWGs
• Replace with simpler fills before export

3D vs 2D Export: What Works in Practice

• 2D views → clean, usable
• 3D views → dense, hard to edit

For drafting, always prioritize 2D exports.

Alternative Workflows (When DWG Is Not Enough)

IFC Export (Interoperability)

Export to IFC when DWG is not sufficient.

• Keeps more structure than DWG
• Used in open BIM workflows

Important:

• Importing IFC into AutoCAD requires a specialized toolset (e.g., AutoCAD Architecture or AutoCAD MEP)
• Not available in standard AutoCAD

Navisworks Workflow (Advanced Coordination)

Use Autodesk Navisworks:

• Aggregate multiple models
• Export to NWD/NWC
• Use in AutoCAD as coordination model

Known Limitations When Converting Revit to AutoCAD

Expect data loss when moving from BIM to CAD:

• Families become blocks or exploded geometry
• Parametric data is lost
• Constraints are removed
• Materials may not translate correctly

This is inherent to the BIM to CAD workflow.

Common Problems and Fixes

Wrong Scale

• Cause: unit mismatch
• Fix: check Revit export units and INSUNITS in AutoCAD

Messy Layers

• Cause: no mapping standard
• Fix: configure layer mapping (AIA/ISO)

Heavy DWG File

• Cause: excessive geometry or hatches
• Fix:
  • use Section Box
  • simplify patterns
  • purge in AutoCAD

Broken Geometry

• Cause: exporting 3D or wrong detail level
• Fix:
  • export clean 2D views
  • adjust detail level in Revit

FAQ

Can AutoCAD open RVT files directly?

AutoCAD cannot open or edit RVT files. It can attach them as a coordination model (read-only).

What is the best format to convert Revit to AutoCAD?

DWG is the standard format for AutoCAD workflows.

What is the difference between Bound and Linked DWG?

• Linked (Xref) → external reference, lightweight, update-friendly
• Bound → embedded, single file, heavier

Why is my DWG file too large?

Usually due to:

• complex hatches
• exporting too much geometry
• lack of model cleanup

Can I keep BIM data in AutoCAD?

No. AutoCAD does not support Revit parametric data.

Can I import IFC into AutoCAD?

Yes, but only with AutoCAD Architecture or MEP toolsets, not standard AutoCAD.

Should I use coordination model or DWG export?

• Use coordination model for visualization
• Use DWG export for editing

This workflow reflects how teams handle Revit to AutoCAD conversion in real projects. If export settings are controlled properly, the DWG will be usable without rework and fit into standard CAD production.
