Create a federated BIM model and detect errors and inconsistencies in your project | usBIM.browser | ACCA software

Create a federated BIM model and detect errors and inconsistencies in your project

usBIM.browser provides a special feature to view multiple BIM models in the IFC format in a single view and create a federated BIM model.

Manage 3D models with the different viewing, translation, rotation and scaling options available in the online BIM viewer according to your needs.

From the federated model, check for interferences and inconsistencies by integrating the BIM viewer with dedicated applications (usBIM.clash and usBIM.checker).

In particular, analyse any possible:

  • geometric interferences between objects, models and drawings (Clash detection)
  • information inconsistencies with respect to rules and regulations (Code Checking).

Experience the project even before realization

With usBIM.browser online DWG viewer, view rendered models of IFC, EDF, RVT or SKP files with advanced architectural visualization functions (rendering, real-time rendering and immersive virtual reality).

Immerse yourself in the BIM model and:

  • verify project effectiveness directly together with any conflicts in an extremely advanced way;
  • try different solutions and options and evaluate their feasibility in real time;
  • improve communication with your client in a clear and engaging manner using extraordinary immersive experiences.


usBIM.browser is one of the 15 free applications included in usBIM.10 allowing you to view and manage large BIM models, documents and data with maximum power and speed, all completely online and from any device.

Going into more detail, with usBIM.browser you can:

  • open and view all documents and models in different formats (IFC, EDF, EDL, RVT, RFA, DAE, OBJ, 3DS, SKP, DXF, DWG, PDF, JPEG, PNG, TIFF, BMP, etc.);
  • browse through large 3D models from any device without having any BIM authoring and without installing any software;
  • share your work without having to exchange files, simply pass a link to your customers and colleagues;
  • navigate in real-time or in immersive virtual reality and analyze every single property of the IFC objects belonging to the digital model;
  • attach data and information to the objects of any 3D model;
  • federate multiple IFC models into a single view, creating tags, annotations, links and georeferenced content.

Using usBIM.browser brings many advantages in the work of technicians, speeding up and simplifying both ordinary and more complex operations. In fact, with a free application, it is possible to have a very powerful tool to manage and navigate even large files, generated with any BIM authoring and without installing any specific software. This means that with usBIM.browser you can easily browse models created with Revit (or any other BIM software) even without having Revit on your computer.

You can browse any type of 3D file: architectural, structural models, plant engineering and ranging from large to small scale without problems and with any device. In addition to viewing the model, you can also query each element or attach information and data to create a real set of files linked together in advanced and complex models but managed with extreme simplicity.

Being browser based, you can view files using any device. In this way you can consult your work files while you are on the train, on the construction site or at a customer's home, even using your tablet or a simple smartphone.

You can manage large files without taking up space on your PC and share your work with extreme simplicity and speed.

You can collaborate with your colleagues and exchange models and files even if you don't use the same software.
