It is a platform neutral, open file format specification that is not controlled by a single vendor or group of vendors. It is an object-based file format with a data model developed by buildingSMART (formerly the International Alliance for Interoperability, IAI) to facilitate interoperability in the architecture, engineering and construction (AEC) industry, and is a commonly used collaboration format in Building information modeling (BIM) based projects.<br /> <br /> == Format ==<br /> IFC defines multiple file formats that may be used, supporting various encodings of the same underlying data.[6]<br /> <br /> * IFC-SPF is a text format defined by ISO 10303-21 (&quot;STEP-File&quot;), where each line typically consists of a single object record, and having file extension &quot;.ifc&quot;. This is the most widely used IFC format, having the advantage of compact size yet readable text.<br /> <br /> * IFC-XML is an XML format defined by ISO 10303-28 (&quot;STEP-XML&quot;), having file extension &quot;.ifcXML&quot;. This format is suitable for interoperability with XML tools and exchanging partial building models. Due to the large size of typical building models, this format is less common in practice.<br /> <br /> * IFC-ZIP is a ZIP compressed format consisting of an embedded IFC-SPF file or IFC-XML file and having file extension &quot;.ifcZIP&quot;.<br /> <br /> == Identification ==<br /> Files begin with signature bytes &quot;ISO-10303-21&quot;. It can be also identified by file schema &quot;IFC2X3&quot;.<br /> <br /> == Sample files ==<br /> * [https://raw.githubusercontent.com/xBimTeam/XbimSamples/master/BasicCreate/SampleHouse.ifc SampleHouse.ifc]<br /> * [https://github.com/xBimTeam/XbimSamples/blob/master/BasicCreate/SampleHouseExtension.ifc SampleHouseExtension.ifc]<br /> <br /> <br /> == Links ==<br /> * [https://en.wikipedia.org/wiki/Industry_Foundation_Classes Wikipedia]</div>
