How to detect changes in IFC models

Need to compare two IFC models? I’ll show you how to detect changes (geometric and informative differences) between two versions of the same model in IFC format

If you are a professional in the construction industry, you surely know how important it is to monitor changes made to a BIM project. However, tracking all the variations over time can become a very complicated task. Especially if the project involves multiple professionals and numerous versions of a 3D model.

Fortunately, there is a solution: to compare 3D models.

You can try now and for free, this tool which allows you to compare accurately, identifying difference of your 3D model versions. In this article I’ll explain in detail how to use it, showing you with a step by step video.

How to detect changes between two 3D Models in IFC format

To compare two different versions of a 3D model in IFC format there is a 3D model comparison tool. You may use directly online without having to install any software on your PC.

The process of using this tool is really simple: after creating a new comparison file on usBIM platform, select the versions of an IFC model you want to compare and start comparing. Once the file comparison process is finished, usBIM platform system generates an information differences detected detailed report.

You may also appreciate geometric differences directly on the model. In fact, thanks to the use of different colors you can easily identify which are the building’s elements that have been:

  • added: building parts that have been added compared to an earlier version of the model;
  • removed: building parts that have been removed compared to an earlier version of the model;
  • changed: building parts that have been modified in one of its parts (height, thickness, etc.) compared to an earlier model version;
  • unchanged: building parts that have remained unchanged from an earlier model version.

In this way, you can monitor all geometric and informative project changes. Improving the project’s quality and reducing inaccuracies or risk of errors.
