xBIM Essentials 4 provides support for Ifc2x2, Ifc2x3 and Ifc4 Addendum 1. This release provides IfcStore, a single point for opening any Ifc file, including XML, STEP21 and IFCZIP formats. All programmatic access to Ifc Entities is through a single interface, allowing one code base to work with all Ifc formats. Ifc4 is the default interface future proofing your development work. This release replaces Xbim Essentials 3 but minor code reafactoring will be required, XbimModel is deprecated in favour of IfcStore.

xBIM Essentials is the core part of the toolkit that deals with reading and writing IFC data files. It does not contain support for geometric operations and 3D visualisation. Use xBIM 3D if you need support for geometry and presentation, its also open source. xBIM is an Open Source Toolkit for developing IFC based applications (BuildingSmart Data model). 3.0 contains a new geometry engine that has a full API to allow geometry constructions, boolean operations and meshing. It provides full support for reading and writing geometry, topology and data in accordance with the Ifc2x3 schema. xBIM reads and writes Ifc, IfcXMl and IfcZip formats. The xBIM project provides packages to convert IFC models to COBie spreadsheets in both UK and US cultures as well as a range of 3D viewing controls for use with Windows forms, WPF, WEBGL and OpenGL platforms. IOS and Android versions are under development.
