[[IfcOpenShell|IfcOpenShell]] is an open source (LGPL 3) software library that helps developers work with the [http://www.buildingsmart-tech.org/specifications/ifc-overview industry foundation classes]  (IFC) file format. The IFC file format can be used to describe building and construction data. The format is commonly used for [https://en.wikipedia.org/wiki/Building_information_modeling building information modelling] (BIM), for example, mechanical loading analysis, and thermal and energy efficiency studies.

IfcOpenShell is primarily a collection of C++ libraries, however, as it has [[Python|Python]] bindings, it can be integrated with programs like [[FreeCAD]] and [[Blender]]. It has support for Windows, Mac, and Linux. IfcOpenShell can be used as C++ developer libraries, through Python modules, via a number of Unix-style command line applications, or via graphical interfaces. The core libraries have support for IFC2X3, IFC4, IFC4.3, as well as custom IFC schemas defined by the user. Supported serialisations include IFC-SPF, IFC-JSON, IFC-XML, and IFC-HDF5.

−
IfcOpenShell supports geometry processing using the [[Open_CASCADE|Open CASCADE]] geometry kernel. IFC geometry may be uniformly triangulated regardless of their original definition.
 
−
 
 
−
IfcOpenShell is also unique in its extensive Python API, which includes hundreds of functions for common IFC manipulation operations. This API supports many aspects of IFC not usually supported in other tools, including cascading geometric coordinate changes, subgraph purging, appending elements, and extensive support for 4D and 5D BIM operations like cost formulas, critical path analysis, and calendar-based scheduling propagation. It is also unique in its support for HDF5 caching, voxel analysis for dealing with less than precise BIM geometry, and semantic SVG-based drawing generation.
