OpenIfcViewer visualising an IFC model with cutting planes

OpenIfcViewer is a new free viewer from CAD and BIM interoperability solutions provider, Open Design Alliance (ODA) that supports all major IFC versions from 2x3 through the 4x2 Bridge candidate.

Features include 3D navigation controls, render modes, predefined views, fast selection, IFC property inspection, and a full IFC hierarchy tree. The viewer also includes more sophisticated features such as scene markup, cutting planes and clash detection.

“We developed OpenIfcViewer with two goals in mind,” said Neil Peterson, ODA President. “First, we want to provide a professional-grade visualization solution for today’s IFC users, who are mostly using IFC 2x3 and 4x0.

“Second, we would like to facilitate the development and adoption of new IFC versions, the IFCs of tomorrow. We already support the 4x2 IFC Bridge candidate released in 2019, and we’re currently working in cooperation with bSI to support the new IFC 4x3 infrastructure candidate, which includes Rail, Road and other IFC extensions.

“IFC 4x3 is being developed by bSI [buildingSMART International] in cooperation with a large group of stakeholders, including bSI members, software vendors, government agencies and various infrastructure domain experts. These stakeholders need tools to create, visualise and work with IFC 4x3 for testing and validation of the new standard. To support these efforts, ODA has committed to adding IFC 4x3 support to OpenIfcViewer by September of this year.”
