IFC VS RVT: what are the key differences in interoperability and data exchange between Revit and IFC?

In the design and construction sector, choosing the right BIM (Building Information Modeling) technology is crucial for effective data management and collaboration among multidisciplinary teams. Revit and IFC (Industry Foundation Classes) are two of the most widely used tools to ensure modeling and data exchange, but each has specific characteristics.

In this article, we will explore the main differences between IFC and RVT, with particular attention to their interoperability and how they impact project management in the construction industry.

IFC VS RVT: two approaches to BIM interoperability

Interoperability between different software is crucial to ensure a smooth collaboration among multidisciplinary teams. Two widely used tools, Revit and IFC, adopt different approaches to this challenge. Let’s take a closer look at how these two solutions compare in terms of interoperability and project information management.

Revit: BIM modeling authoring and proprietary limitations

Revit is a BIM software developed by Autodesk, one of the players in the construction software industry. It offers advanced features for the design and management of buildings and infrastructures, allowing for three-dimensional modeling. However, its proprietary nature presents some challenges in terms of interoperability:

• proprietary format: Revit uses the .rvt format, optimized for the Autodesk ecosystem but requiring conversions for use with other BIM software;
• data complexity: the data structure of Revit is detailed, with complex relationships between elements and specific family definitions that may not translate perfectly into other formats;
• compatibility limitations: although Revit can import and export IFC files, this interoperability is often limited to specific types of data and may not capture all the nuances of the Revit model.

IFC: the open standard for interoperability

IFC, or Industry Foundation Classes, is a standardized open file format that facilitates the exchange of BIM data between different software platforms. Its main features include:

• neutral format: IFC is designed to be used with any BIM software, promoting collaboration among teams using different tools;
• flexibility: the IFC structure is more flexible and less specific than proprietary formats, allowing for greater adaptability to different design scenarios;
• continuous evolution: IFC standards are constantly updated to improve interoperability and data exchange capabilities in the construction sector.

Challenges and advantages in using Revit and IFC

One of the main strengths of Revit is its integrated environment, which allows not only for design but also for managing all construction-related information within the same ecosystem. This aspect makes Revit particularly efficient, especially for projects developed entirely within the Autodesk environment, thanks to specific and optimized tools.

However, there are some critical issues. One of the main challenges is the limited compatibility with software that does not belong to the Autodesk suite. When working with teams using other platforms, there is a risk of data loss during file conversion. This often requires the need to perform multiple conversions, complicating collaboration and increasing the chances of error.

On the other hand, the IFC format (Industry Foundation Classes) was created specifically to promote interoperability between different software platforms. This makes it an ideal tool for facilitating collaboration in international and multidisciplinary contexts, where communication between different software is essential. Moreover, using IFC supports transparency and compliance with standards, particularly relevant in public projects, where maintaining uniform quality standards is essential.

Despite its numerous advantages, IFC also presents challenges. One of these concerns the need for additional configurations to ensure that data is interpreted correctly by all involved software. Additionally, its flexibility, while advantageous, can lead to different interpretations depending on the software used, generating possible discrepancies in the final results. Finally, it is possible that some specific information from the native software may be lost during conversion to the IFC format, requiring additional verification to ensure the completeness of the transferred data.

usBIM.revolution: the bridge between IFC and RVT

One of the main difficulties in using Revit with the IFC format is the smooth management of data during import and export. usBIM.revolution, a powerful plugin, solves many of these issues, enhancing interoperability between Revit and IFC and optimizing workflow.

With the usBIM.revolution plugin, it is possible to create a direct link between the Revit BIM model and the corresponding IFC model hosted in the cloud on the usBIM platform. This link ensures that all changes made to the collaborative IFC model are synced in real-time with the BIM model in Revit​.

Advantages of the usBIM.revolution plugin

• cloud management: allows working on the IFC file directly in the cloud, synchronizing changes in real-time with the Revit model, without the need for complicated conversions. Working in the cloud enables unprecedented collaboration among distributed teams;
• IFC data editing and collaborative editing: users can easily edit entity names, select and modify IFC classes, add property sets and properties, and copy properties between entities directly in the cloud environment;

• advanced import: the plugin allows importing IFC files into Revit while retaining all new class and property information, ensuring a smooth data transition;
• optimized export: it enables exporting IFC files from Revit while maintaining all additional information, such as properties and classes, directly managed through the plugin;

• data visualization: after export, the IFC file can be viewed in any compatible viewer, allowing for immediate verification of data accuracy;
• advanced features: allows for modifying multiple entities simultaneously or quickly copying properties between entities, improving workflow efficiency;

This plugin solves many of the issues associated with managing IFC files in Revit, improving communication among various stakeholders and ensuring that data is always up-to-date and accurate​.

Revit and IFC play fundamental roles in the construction industry, but with substantial differences regarding data interoperability. Revit offers an integrated and optimized BIM environment for Autodesk users, while IFC provides an essential open standard format for projects that require collaboration across different software platforms.
