ACCA software at the buildingSMART International Summit 2025
ACCA software confirms its presence at the event and, as a Silver sponsor, will hold a technical session on March 19 during which the new openBIM® standard IFC5 and the usBIM.ifc5 application will be discussed at the Technical Room of bSI.
During the event, participants will also be able to visit the stand n°J02 at Expo Hall 3 to discover the innovative openBIM® software developed by ACCA software.
ACCA software’s contribution to the implementation and validation of the IFC5 standard
ACCA software, in addition to actively participating in the development of the new IFC5 standard, is contributing to the testing phase by providing its technology for the online visualization of IFC5 data currently being defined.
usBIM.ifc5, an application dedicated to managing IFC5 models of any size, allows users to:
- convert old IFC files to the new IFC5 format (.IFCX);
- explore workflows emerging from the USD ecosystem;
- continuously adapt to the evolution of the IFC5 standard, integrating feedback from the working group.

Example of displaying the data structure of a BIM model in IFC5
usBIM.ifc5 is part of the broader usBIM ecosystem, which currently supports integrations with openBIM® standards such as bSDD, IDS, BCF, and others, ensuring full compliance with openBIM® workflows and offering a wide range of additional features. Future updates will introduce these integrations in usBIM.ifc5 as well.
