BIMx Frequently Asked Questions

by GRAPHISOFT, Marton Kiss, Katalin Götz, Tünde Ómajtényi and Csaba Kézér · updated: 02.27.2015

What makes BIMx for mobile devices unique compared to other 3D viewers?

Most 3D model viewers for the mobile devices are generic purpose viewers. This means their navigation functionalities are basically limited to 3D orbit, pan and zoom. BIMx has a lot more to offer than that (selective list):

  • It is a full “natural” building explorer environment – with gravity and egress recognition just to mention examples – that is with all the necessary UI features that make or break great user experience
  • It has sophisticated visual filters (views) to provide a high quality architectural presentation environment such as stereoscopic view etc.
  • It is integrated with an ecosystem of the desktop application and the online model sharing community

Model Transfer

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

If you use ArchiCAD 17 or newer, you have two options:

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

If you have ArchiCAD 16, you can export the model with the ‘File/Export for BIMx…’ option


How can I send BIMx models to my clients?

Use GRAPHISOFT’s BIMx Cloud service to share your model with others. There are two ways to upload your model:

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

What is the BIMx Model Transfer Service?

The BIMx Model Transfer Service is a “cloud-service” to share BIMx models with Colleagues and Customers.

Find more info about the BIMx Model Transfer Service here.

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 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 either from ArchiCAD (BIMx Hyper-model) or from BIMx Desktop application (BIMx 3D Only 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.

Logon 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?

Registration requires an ArchiCAD/BIMx installation and can be initiated in the following ways:

  • Register from scratch
  • Login (register) with Google or Facebook ID via ArchiCAD or BIMx Desktop Application

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?

The BIMx for Android version was mainly developed to explore 3D models on tablets. Many of the most popular Android tablets have been also tested: 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 memory. The performance speed (FPS) mostly depends on the capabilities of the GPU.

For detailed System Requirements please check this article.


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.


Is there a difference between the iOS and the Android versions of BIMx?


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

Yes, all versions have BIMx Add-On (BIM Explorer) as a default part of the ArchiCAD package.

  • 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.
