Key Features

  • Interactive 3D model navigation and exploration.
  • Embeds BIM data, including geometry, parameters, and attributes.
  • Supports linking to 2D drawings and documentation.
  • Optimized for mobile and desktop viewing without requiring original BIM software.

Best For

  • Sharing interactive BIM models with non-technical stakeholders.
  • Providing access to project data on tablets and smartphones.
  • Visualizing detailed architectural and engineering designs.
  • Facilitating collaboration between design and construction teams.

Less Ideal For

  • Editing or creating BIM models (requires original BIM software).
  • General-purpose 3D model sharing (e.g., for game development or animation).
  • Archiving raw BIM project files (use native formats like PLN).
  • Sharing simple 2D drawings without 3D context.

Common Use Cases

  • Client presentations of architectural designs.
  • On-site access to model information for construction teams.
  • Design review meetings among project stakeholders.
  • Visualizing complex building systems and components.

How to Open It

  1. Download and install the free Graphisoft BIMx application from your device's app store (iOS, Android).
  2. Install the Graphisoft BIMx desktop viewer on Windows or macOS from the Graphisoft website.
  3. Open a .bimx file directly within the BIMx application or viewer.
  4. BIMx files can also be accessed via the BIMcloud platform for collaborative workflows.

What is a .bimx file?

BIMx is a file format specifically designed for sharing and visualizing 3D building information models. It allows architects, engineers, and clients to explore complex building designs interactively, even without specialized BIM software. The format embeds all the necessary model data, including geometry, BIM attributes, and 2D documentation, into a single file for easy distribution. This makes it an excellent tool for design reviews, client presentations, and on-site access to project information.

Common Problems with .bimx Files

⚠️ File is too large for sharing.
Ensure the model in Archicad is optimized before exporting to BIMx, and consider publishing only relevant model elements.
⚠️ Cannot open BIMx file on desktop.
Download and install the official Graphisoft BIMx desktop viewer for your operating system.
⚠️ Missing linked 2D documentation.
Ensure that all necessary 2D drawings were correctly published or linked within Archicad before creating the BIMx file.

Frequently Asked Questions

Can I edit a BIMx file?

No, BIMx is a viewing format. You need the original BIM software (like Graphisoft Archicad) to edit the model.

Is BIMx free to use?

Yes, the BIMx viewer application for desktop and mobile devices is free to download and use for viewing BIMx models.

What is the difference between BIMx and IFC?

BIMx is a proprietary format optimized for interactive visualization and sharing by Graphisoft, while IFC is an open, industry-standard format for BIM data exchange.

Technical Details

The BIMx format is a proprietary container that packages a Graphisoft Archicad model into a navigable 3D environment. It optimizes the model data for efficient real-time rendering and interaction, often employing proprietary compression techniques. The file typically includes a rich set of metadata and can link to 2D drawings and documentation.

Did You Know?

BIMx allows for hyper-model functionality, enabling navigation between the 3D model and linked 2D documentation seamlessly.
The format is designed to be highly performant, allowing complex building models to be explored smoothly on mobile devices.

Security Information

BIMx files are generally safe as they are intended for viewing and do not contain executable code. However, always ensure you download the BIMx viewer from official sources to avoid malware.
