If you want to share a Revit model in a web viewer, create a virtual walkthrough, or present a design in VR, exporting your project to the GLB format is often the first step.
This guide explains everything you need to know about exporting Revit to GLB, using the Leia glTF Exporter and what you can do with the file afterward. In brief, all you need to do is install the Leia glTF Exporter add-in and and export your Revit model as a GLB file. After export, the file can be uploaded to VR platforms such as Visiofy to create binteractive, walkable virtual space from architectural models.
GLB is a lightweight, web-friendly 3D file format that combines geometry, materials, and textures into a single file. Because of its portability and broad compatibility, GLB has become a popular choice for Revit model sharing, Revit VR presentations, and browser-based visualization tools.
Basically, GLB is the binary version of the glTF (GL Transmission Format) standard developed by the Khronos Group.
A GLB file contains:
Unlike formats that store assets in multiple files, GLB packages everything into a single file, making it easy to transfer, upload, and share.
Because of this, GLB has become one of the most widely supported formats for:
Many modern Revit web viewer platforms rely on GLB or glTF files as their preferred input format.
Autodesk Revit was primarily designed as a Building Information Modeling (BIM) platform rather than a real-time visualization tool.
While Revit supports formats such as:
it does not currently include a built-in GLB exporter.
This means users who want to publish models to modern web viewers or virtual presentation platforms must use a third-party Revit GLB exporter.
One of the most straightforward options is the Leia glTF Exporter.
The overall workflow is simple:
The actual export process takes only a few minutes once the plugin has been installed.

After installation:
The exporter converts the Revit model into a web-friendly GLB file while preserving geometry and materials where possible.
This workflow is often preferred over older formats because GLB files are significantly easier to use in modern visualization pipelines.
Before exporting, it's worth reviewing your model and settings.
Remove:
This helps reduce file size.
Materials often contribute heavily to the final appearance.
Verify:
before exporting.
Large BIM projects can contain far more detail than necessary for presentation purposes.
Consider simplifying:
to improve performance.
Many exporters allow exporting only the currently visible view.
This can be useful when creating:
rather than exporting the entire project.
If materials appear incorrectly after export:
Complex BIM models can create very large GLB files.
Reduce size by:
If the model loads slowly:
Always verify that export units remain consistent between Revit and the destination platform.
Once you successfully export Revit to GLB, the file can be used in numerous ways.
GLB files can be uploaded to browser-based viewers, allowing users to inspect the model without installing specialized software.
Instead of sending screenshots or PDFs, you can provide an interactive experience where clients can explore the design themselves.
A GLB model can become the foundation of an interactive Revit virtual walkthrough, enabling users to move through spaces in real time.
Many VR platforms support GLB directly or through conversion workflows.
This makes GLB an excellent format for Revit VR presentations.
Interactive models often communicate design intent more effectively than static images alone.
Clients can better understand:
before construction begins.
Once your Revit model has been exported to GLB using the Leia glTF Exporter, you can upload it to Visiofy.
Visiofy converts architectural models into browser-based, walkable virtual spaces that can be explored from any modern device.
Unlike static renderings or screenshots, visitors can move through the design themselves and experience the project from a first-person perspective.
Benefits include:
For architects, residential designers, and housebuilders, this provides a practical way to transform a Revit model into a more engaging presentation experience.
