  • Navigation works the same way on both platforms with the 3D model.
  • There are slight OS specific differences in the user interface, location of the settings, and in the file management.
Where can I download the Windows version of BIMx mobile?

The BIMx mobile application is only available for iOS and Android devices. BIMx Desktop Viewer is available for Windows platform, but will require a mouse and a keyboard.

I have my BIM project created in ARCHICAD, how can I export it as a BIMx model?

If you use ARCHICAD 20 & 21, do the following:

  • Publish a BIMx Hyper-model for your mobile device with the BIMx PRO functionality
    • File / Publish BIMx Hyper-model, or
    • Navigator / Publish

If you use ARCHICAD 17, 18 or 19, you have two options:

  • Save a regular BIMx 3D model from ‘File/Save as…/BIMx’
  • Publish a BIMx Hyper-model for your mobile device with the BIMx PRO functionality

If you have ARCHICAD 16 or older you can export the model with the ‘File/Export for BIMx…’ option

What is the difference between a legacy BIMx 3D model and a Hyper-model?

In ARCHICAD 19 and earlier versions of ARCHICAD:

  • 3D Window > File – Save as menu command saves a 3D only BIMx model. This is a legacy format, not supported by ARCHICAD 20.
  •  File –  Publish BIMx Hyper Model command publishes a hyper-model. (This opens the Wizard that helps you through the publishing process. It has almost the same functionality as the Publisher, but a few options are only available in the Publisher. But it is good to start with the Wizard.).
  •  From Publisher you can publish a hyper-model.


  • There is no Save as command
  •  File –  Publish BIMx Hyper Model command publishes a hyper-model
  •  From Publisher you can publish a hyper-model.
What is the size limitation of a 3D model component in a BIMx hyper-model?

When publishing a hyper-model, the 3D model component of the hyper-model cannot exceed the size of 400 MB. You will face upload failure if its size exceed this limit.

How can I send BIMx models to my clients?

You can use GRAPHISOFT’s BIMx Model Transfer service free of charge to share your model with others.

You can also publish your model locally, before uploading it on a cloud platform.

Alternative options to transfer your BIMx models to Android and iOS devices can be found here:

How to save a .bimx file format from BIMx Desktop Viewer

From ARCHICAD 20, a standalone version of BIMx Desktop viewer can be installed. It is not possible to save a .bimx file from the Desktop application. It acts as a viewer only.

What is the BIMx Model Transfer Service?

The BIMx Model Transfer Service is a “cloud-service” to share BIMx models with Colleagues and Customers. Models on the BIMx Model Transfer Site are publicly available, but Offices with an active Software Services Agreement are entitled to an additional 5 GB of private storage as well. Please consult the Terms of Use to get full details on content storage.

I can only publish models to my public folder, how can I publish privately?

Users with Education, Trial and Commercial (without Software Services Agreement) can only upload their models to a public folder on the BIMx Model Transfer site (with a storage limit of 5GB).

In order to be able to publish BIMx hyper-model privately, an active Software Services Agreement (SSA) contract is needed, it gives access to a 5GB private storage. Please consult the Terms of Use to get full details on content storage.

How can I register my company on the BIMx Model Transfer site?

When you upload a BIMx model to GRAPHISOFT’s cloud service for the first time with your protection key, you will be requested to create a so-called BIMx Company Account where you can store your uploaded models. Follow the steps of the registration process here. Also, your Company gets automatically registered once you change over to software license keys.

Who can access BIMx models on the BIMx Model Transfer Site?

The BIMx Model Transfer Site is accessible in any of the following ways:

  • Through direct page URL:
  • Through direct links to uploaded BIMx models’ download page
  • Through built-in links from mobile devices (iPad/iPhone)

Users can search/browse and download Public BIMx models from the site without registration or log-in.

Who can upload BIMx models onto the BIMx Model Transfer Site?

BIMx models can be uploaded from ARCHICAD (BIMx Hyper-model). The first time BIMx users want to publish their models to the Transfer Site they will be required to register. Consult this article to read more about setting up the upload environment.

Login to the BIMx Model Transfer Site is only required to manage one’s uploaded models (edit model details/move or delete models etc.).

What are the different ways for people to register to the BIMx Model Transfer Site?

With Registering a GRAPHISOFT ID you get access to all of our cloud services:

If you have already registered to any of the above sites you can use the same account to upload BIMx models and log in to the BIMx Model Transfer Site.

What is the difference between My models and My Company tabs in the BIMx profile?

Once signing in to your BIMx profile you can see the My models and My Company tab pages on the top dividing your uploaded BIMx models into two sections:

  • The My models tab contains all models you have uploaded from a Trial or Educational version of ARCHICAD
  • The My Company tab contains all models you have uploaded using your Company license key
What are the different visibility types for my models?
  • Public
    • Accessible by anyone visiting the BIMx model transfer site
  • Private
    • Accessible only by user having the URL to access the model download page
  • Private (password protected)
    • Accessible only by user having the URL to access the model download page, and
    • Downloadable only by user having received the password from the model owner

How to upgrade to the latest BIMx version?

Since the release of ARCHICAD 17, BIMx is fully functional with the ARCHICAD license in most Countries (separate BIMx license is only necessary in Japan and Switzerland). To upgrade your current license please contact your local ARCHICAD reseller.

What are the system requirements for BIMx Desktop version?

For detailed description, see System Requirements for BIMx Desktop Viewer.

What are the recommended mobile devices to run BIMx?

iOS: BIMx works well with the newer iPads and iPhones having at least 1 GB of RAM available

Android: Many of the most popular Android tablets have been tested with BIMx: Samsung, Asus, Motorola, Archos, Sony etc. As a general rule, the capability of the processor, memory and GPU influence the usage of BIMx models: more models can be smoothly managed with more RAM. The performance speed (FPS) mostly depends on the capabilities of the GPU.

For detailed System Requirements please check this article. Read more on how to optimise BIMx files for mobile use.

What kinds of license types can I use to create BIMx models for clients?

For all available options see: BIMx License Types

What can cause sudden restart, quit or freeze on my Android or iOS device?

The RAM capability of your device is responsible for managing the BIMx models. If the application restarts, freezes or quits, probably the memory of the device is full and the OS stops the application. To resolve this please follow the model optimising tips in the the BIMx Optimization article.

Can I use BIMx Desktop Viewer with Start Edition or with Educational/Trial versions?

Yes, all versions until ARCHICAD 19 have BIMx Add-On (BIM Explorer) as a default part of the ARCHICAD package. In ARCHICAD 20, BIMx Desktop viewer needs to be downloaded separately, here. While in ARCHICAD 21, BIMx Desktop Viewer will be installed as part of the ARCHICAD installation.

  • the .bimx files saved in the Trial version can be opened only on the computer where they were saved
  • the Educational version’s saved files have an Educational version watermark.
Where can I find the installed desktop application(s)?

Default BIMx Add-On folder (up to ARCHICAD 19):

  • Mac: /Applications/GRAPHISOFT/ARCHICAD version/Add-Ons/BIMx
  • PC: C:\Program Files\GRAPHISOFT\ARCHICAD version\Add-Ons\BIMx
  • From ARCHICAD 20: BIMx Ad-On folder does not contain the file anymore, if BIMx Desktop Viewer needs to be downloaded it can be done from here.

Default BIMx Desktop Viewer folders:

  • Mac: /Applications/GRAPHISOFT/BIMx Desktop Viewer
  • Windows: C:\Program Files\GRAPHISOFT\BIMx Desktop Viewer
Can I use Space Navigator from 3D Connexion with BIMx?

No, it is not supported at the moment.

Can I perform a Global Illumination render in the background?

Up to version 19, both in ARCHICAD at the publishing of the BIMx Hyper-model and in BIMx Desktop viewer it is possible to render the Global Illumintation in the background, you can simply alt tab/cmd tab to an other application and the BIMx GI calculation will run in the background. From ARCHICAD 20 it is only possible to do so at the publishing step of the BIMx Hyper-model in ARCHICAD, it is not supported anymore in the latest BIMx Desktop viewer application.

Does BIMx have Anti-aliasing?

No, it is not supported at the moment on the desktop version, only on the mobile version.
