Convert 3D models to IFC files

With usBIM.viewer + open, convert, integrate and export in IFC file format 3D models and objects from many formats like AutoCAD® (.dwg), SketchUp® (.skp), 3D Studio Max® (.3ds) and many others .. even without having your own BIM software!

Turn your 3D virtual model into the IFC standard format, integrating the graphical representation with any technical, sales, structural, plant engineering and cost, etc. information.

Easily add IFC properties

With usBIM.viewer + add custom IFC properties to 3D models and objects and integrate the information with further technical, commercial, structural, plant, metric and many other data ... without having to own BIM software!

Easily implement all the specifications necessary to completely define the BIM model.

Use the advanced features of a BIM authoring for free to implement the information contained in the BIM model and make communication during the design, execution and maintenance of the most efficient and reliable work.

The main features of usBIM.viewer +

Viewing the 3D model

With usBIM.viewer +:

  • navigate the 3D virtual model visually with the help of typical Zoom, Rotate and Pan features.
  • easily view portions of the BIM model. 

Specific visibility management, coloring and transparency features, applied and defined by level, type of element or single entity allow the user to conduct very detailed analysis.

Display of IFC information

With usBIM.viewer +:

  • Work in graphical mode
  • Select the entities in 3D or in the tree structure of the IFC file
  • View and verify the information of each BIM element (volumes, areas, surfaces, distances, weights and many others)

Comparison of multiple 3D models

With usBIM.viewer +:

  • compare multiple 3D models in one view
  • simultaneously view all design phase aspects (architectural, structural, technical systems, etc.).

Specific functions ( Snap, Move, Rotate, Align ) let you easily overlay and update different BIM models.


With usBIMviewer +:

  • highlight specific properties of a BIM object using the #TagBIM
  • make important information easily visible in other activities of creating or updating the BIM model (design, execution or maintenance phases of the asset)
  • use the advanced search features to find information that others have highlighted in the model using #TagBIM

The #TagBIM managed by usBIM.viewer + are recognizable by any other BIM Authoring or BIM Tool application . The digital recognition allows to automate the execution of activities or the preparation of project documents (eg: cost estimates, facility management plans, etc.). Connecting the most relevant information through the #TagBIM feature saves time and avoids making mistakes thanks to the automatic recognition of the software and the easy reading of data by participants.

Creating Groups and Selection Filters

With usBIM.viewer +:

  • create custom views with Filters and Selection Groups
  • speed up and simplify the understanding of the BIM model

With selection groups and saving views, quickly analyze the BIM model , single or federated, and eliminate any waste of time due to manual operations.

FAQ (Frequently Asked Questions)

With usBIM.viewer + you can open and view BIM templates in IFC file format for free from any BIM Authoring such as Edificius®, Revit®, ArchiCAD®, Allplan®, Tekla®, VectorWorks® and many others without the need of your own BIM software

You can even transform your 3D project into a standard IFC format and use the advanced IFC writing capabilities to create your new additional data for each BIM model.

The IFC standard (acronym for Industry Foundation Classes) is an open file format developed by buildingSMART (International Alliance for Interoperability, IAI) to facilitate interoperability between the various professional roles in the construction industry (architects, engineers, contractors, clients, etc...) independently from the software solutions adopted used for their daily work.

usBIM.viewer + adopts the IFC standard because it is functional to the BIM (Building Information Modeling) process and is a universally recognized standard ( ISO 16739 ).

IFC is the recognized standard used to transmit data from the best authoring and BIM tools certified by Building Smart International.

YES. With usBIM.viewer + you can collaborate in the BIM process in full security as it is software certified by buildingSMART .

BIM (Building Information Modeling) is increasingly a reality that implies collaboration, interoperability and coordination between the different actors of the construction industry. With usBIM.viewer + you can work safely with all the best Authoring and BIM Tools certified by Building Smart International.
