Autodesk Revit has established itself as an essential tool for building and construction professionals. Its ability to create 3D parametric models that integrate project data makes it a preferred solution for Building Information Modeling (BIM). This article explores the essential aspects of data interoperability with Revit, a crucial issue for multidisciplinary collaboration in construction projects.

History and Evolution of Revit

Revit was originally developed by Charles River Software, founded in 1997 by Leonid Raiz and Irwin Jungreis, former developers of PTC's Pro/Engineer software. Their goal was to bring parametric modeling, common in mechanical CAD, to the building industry. The first version of Revit was launched on April 5, 2000.

The company was renamed Revit Technology Corporation in January 2000, then acquired by Autodesk for $133 million in 2002. This acquisition accelerated the development and improvement of the software. The name "Revit" is actually a contraction of "Revise-Instantly," reflecting the software's ability to update all linked elements when a modification is made to one part of the model.

Over the years, Revit has been enriched with new features:

• 2005: Introduction of Revit Structure
• 2006: Launch of Revit MEP
• 2011: Release of Dynamo in beta version
• 2012: Introduction of Revit LT, a lighter version of the software

In 2025, more than 14,302 companies worldwide use Revit as a CAD tool, with 1,610 specifically in the field of architecture. This massive adoption demonstrates its dominant position in the AEC (Architecture, Engineering and Construction) sector.

Revit's Geometric Engine and Its Specificities

Revit's geometric engine is based on specific technical choices that distinguish it from other CAD systems. Unlike software such as Inventor or AutoCAD, Revit uses parameterized curves and surfaces to represent geometric edges and faces respectively.

A notable peculiarity concerns the representation of cylindrical shapes: in Revit, a complete cylindrical face is generally divided into two half-cylinders. This approach results from a deliberate choice in the design of Revit's geometric core to avoid ambiguities in surface parameterization.

Developer John Mitchell from the Revit team explains this technical choice:

"Revit uses parameterized curves and surfaces to represent the geometry of edges and faces. For example, a spherical surface essentially uses latitude and longitude as coordinates. By prohibiting closed edges and faces, we represent the sphere using two hemispherical faces, which eliminates any ambiguity when determining coordinates."

This approach, although it may seem counter-intuitive for users accustomed to other CAD systems, offers advantages in terms of consistency and reliability of the parametric model.

Exchange Formats Supported by Revit

Revit supports a wide range of exchange formats to facilitate interoperability with other CAD and BIM applications. This flexibility allows AEC professionals to integrate Revit into various workflows and exchange data with different disciplines.

Standard Import and Export Formats

Revit supports the following formats for data import and/or export:

• DGN (MicroStation Design File): Used to exchange data with Bentley MicroStation users
• DWF/DWFX (Design Web Format): Lightweight format developed by Autodesk for sharing and visualization

• IFC (Industry Foundation Classes): Essential open format for BIM interoperability
• SAT (ACIS SAT): File format for solid geometry exchange
• SKP (SketchUp): SketchUp native format, used for importing architectural concepts

Formats Added in Revit 2023

Version 2023 extended interoperability capabilities with the addition of three important formats:

• AXM (FormIt): Autodesk FormIt native format, now supported for import and direct linking in Revit
• OBJ (Wavefront Object): Versatile 3D exchange format, initially supported for import in version 2022.1, then for linking in version 2023
• STL (Stereolithography): Standard format for 3D printing and additive manufacturing

Format Added in Revit 2025

These developments demonstrate Autodesk's ongoing commitment to improving Revit's interoperability with other platforms and formats, thus facilitating collaborative workflows in the AEC sector.

IFC4 Format Support: A Decisive Step Towards Complete Interoperability

The IFC (Industry Foundation Classes) format is essential for BIM interoperability, and Revit offers complete support for this format. For imports, Revit supports IFC files based on IFC4, IFC2x3, IFC2x2, and IFC2x standards. For exports, it supports IFC4, IFC2x3, and IFC2x2 standards.

Advantages of IFC4

IFC4 represents a major advancement over previous versions, with significant improvements:

1. File size reduction : IFC4 offers much more efficient ways to store geometry, both for meshes and parametric shapes. For example, an IFC file produced from Revit of a single object weighing 16,098 kB can be reduced to 4,487 kB when re-exported in IFC4, without any loss of geometric detail.
2. Better mesh representation : The new support for tessellated forms allows a much more efficient description of meshes compared to the faceted BREPs of IFC2X3.
3. Improved parametric geometry support : IFC4 enhances Revit's ability to export parametric geometry, thus preserving the intelligence of the model.

IFC Export Tools in Revit

Autodesk regularly updates Revit's IFC exporter to integrate new features and fix bugs. The IFC Export Alternate UI offers additional flexibility in choosing export options. Both tools are available on the Autodesk App Store and must be downloaded and installed manually.

For English-speaking users, the "IFC Exporter for Revit" provides a set of parameter sets that can be used directly for exports. It is possible to add, delete, or modify an existing parameter set to adapt it to the specific needs of the project.

Navisworks is a 3D design review software developed by Autodesk that plays a crucial role in the CAD interoperability ecosystem. As a coordination and project review tool, it allows combining 3D models from various sources and formats to create a complete and coherent project model. Let's discover in detail how Navisworks facilitates CAD data exchange and optimizes collaborative workflows in construction projects.

History and uses of Navisworks software

Acquired by Autodesk, Navisworks has established itself as one of the most reliable review and coordination tools used by construction project managers and VDC (Virtual Design and Construction) professionals. Its development was guided by the need to create a common platform where different models designed on various platforms can be analyzed and coordinated.

Main uses and benefits

Navisworks is primarily used for:

• Detecting and resolving conflicts between different disciplines (structure, MEP, architecture)
• Coordinating complex projects
• Construction simulation and planning (4D)
• Project visualization for client presentations
• Estimation and quantification for quotes (5D)

The software offers considerable advantages in terms of collaboration, including:

• Early detection of conflicts before construction
• Complete project visualization
• Temporal simulation of the construction process
• Accurate project estimation
• Improved risk management
• Streamlined communication between stakeholders

The Navisworks geometric engine

The Navisworks geometric engine is specially designed to optimize rendering and spatial analysis of complex models. It uses simple tessellated geometry that enhances performance when handling large models.

Structure of the geometric engine

Navisworks employs a spatial graph for all spatially oriented operations such as rendering, selection, collision detection, and clash detection. The leaves are self-contained instances comprising a bounding box, transformation, material, and geometry definition, all stored in a format optimized for rendering.

To efficiently support spatial queries, Navisworks uses a hierarchy of spatial bounding boxes (a variant of R-tree). This structure allows the software to quickly process large and complex models.

Data organization

The Navisworks data model is written in separate streams, in the order they are typically read:

• The logical scene graph
• The spatial hierarchy
• The set of instances
• Separate streams for each functionality with its own metadata (clash tests, saved viewpoints, selection sets, etc.)

This organization not only allows loading data on demand but also adding new functionalities without having to modify the file format, thus ensuring compatibility with previous versions.

Navisworks native file formats

Navisworks uses three native file formats, each with specific characteristics and uses:

NWD Format

An NWD file contains all model geometry along with Navisworks-specific data, such as review annotations. This format can be considered as a snapshot of the current state of the model. NWD files are very lightweight, compressing CAD data up to 80% of their original size.

NWF Format

An NWF file contains links to the original native files (listed in the selection tree) along with Navisworks-specific data. No model geometry is saved with this format, which makes an NWF file considerably smaller than an NWD.

NWC Format (cache files)

By default, when you open or append native CAD files or laser scans in Navisworks, a cache file is created in the same directory and with the same name as the original file, but with the .nwc extension. These files are smaller than the original files and speed up access to frequently used files.

Optimization of Format Conversions

For exports to .SAT, a common scale factor issue (division by 10) occurs when importing into AutoCAD. The solution is to manually edit the SAT file via a text editor by modifying the 'units per meter' value before reimporting.

When generating .DXF files for plasma cutting, maintaining a 1:1 scale in the drawing view preserves dimensional integrity.

For .STL exports intended for 3D printing, reducing the mesh resolution in the export parameters avoids oversized files (6 GB) and excessive processing times.

Management of Complex Imports

Importing SolidWorks files (.sldprt) requires the presence of all referenced components in the same directory. A tip is to use lightweight mode for assemblies exceeding 1,000 parts, reducing memory load by 40%.

For Rhino models (.3dm), activating the "Merge surfaces" option during import avoids topology errors.

Advanced Automation

The integrated Python script editor allows automation of recurring conversions. A community script allows converting .STL to .STEP in one operation, bypassing the limitations of direct mesh import.

For export batches, setting up predefined profiles with geometric tolerance options (0.001 mm) and removal of empty entities accelerates processing by 70%.

Resolution of Common Problems

In case of corrupted files, Alibre's automatic repair function analyzes defective segments while preserving assembly references.

For version incompatibilities, systematically exporting in STEP AP242 preserves technical metadata during exchanges with obsolete systems.

A recurring problem with Parasolid files (.x_t) is resolved by forcing the binary format (.x_b) for complex assemblies.

Multi-CAD Collaboration

Using the 3D PDF format including PMI (Product Manufacturing Information) allows design review without a CAD license.

For cloud collaborations, integration with Autodesk Drive synchronizes external references while keeping track of modifications.

A little-known tip is to export bills of materials (.AD_BOM) in .CSX for direct integration into ERPs.

Good Archiving Practices

Favoring STEP AP242 with ZIP compression for long-term archiving ensures readability for 15 years according to ISO 10303 standards.

Systematically adding metadata (author, version, units) in the .AD_PKG file properties facilitates traceability.

For sensitive projects, double exporting in JT (visualization) and STEP (exact geometry) covers all reuse needs.

2. Time Saving: Particularly beneficial for complex models with many PMIs
3. Reduced Interpretation Errors: Manufacturing information is directly linked to the relevant geometric elements
4. Better Interoperability: The STEP AP242 format is considered the best STEP format to use because it is compatible with MBD/MBE (Model-Based Enterprise) workflows
5. Universal Viewing: STEP AP242 files can be viewed in eDrawings, allowing partners without SolidWorks to view models with their PMIs

Workflow Integration

SolidWorks MBD integrates seamlessly into existing workflows :

• Step AP242 files can be attached to eDrawings files when publishing, allowing both the lightweight visualization and the complete geometric data to be shared.
• Users can view, extract, or delete STEP attachments directly from eDrawings.
• The MBD module also allows publishing to other formats such as 3D PDF, facilitating information sharing with partners without CAD tools.

The adoption of SolidWorks MBD with STEP AP242 support represents an important step towards the Model-Based Enterprise (MBE), where the 3D model becomes the primary reference for all stages of the product lifecycle.
