A BCF file (.bcfzip) is transferred from user to user, edited and returned. There are two different ways to utilize BCF – via a file-based exchange or via a web service. The file-based exchange workflow is relatively straightforward and is a process most people are used to using. Developers can find more information about supporting BCF in their products through the open GitHub repositories here and here. Their desire to leverage open communication technology for IFC-based workflows led to prototyping, and eventually fully developing, BCF with other ISG members.īCF is now a buildingSMART International openBIM standard, like IFC and the Data Dictionary (bSDD), open for all to use. The development of BCF started in 2009 and was originally conceived by two members of the buildingSMART International Implementation Support Group (ISG), Solibri and Tekla, along with the Institute for Applied Building Infomatics (iabi) at the Munich (Germany) University of Applied Sciences. More specifically, BCF works by transferring XML formatted data, which is contextualized information about an issue or problem directly referencing a view, captured via PNG and IFC coordinates, and elements of a BIM, as referenced via their IFC GUIDs, from one application to another. This can be done by utilizing a file exchange between software platforms or using a RESTful service that connects software platforms directly or to a dedicated 3rd-party BCF server acting as the hub for such communications. In general, the BIM Collaboration Format (BCF) allows different BIM applications to communicate model-based issues with each other by leveraging IFC models that have been previously shared among project collaborators.
