![]() – Use External IFC ID where available: Check this box if you are using the externally referenced model elements as reference elements only, and you will not export a new IFC model with these elements. These IFC IDs are stored in both the IFC models and the BCF files. ![]() Check the Use External IFC ID box depending on your workflow:īackground: The BCF supporter applications identify BCF comment-related elements in the IFC model based on their IFC IDs. ARCHICAD keeps the elements' original IFC Global Unique ID, to keep track of element iterations through multiple exchanges of information.Ĥ. In BCF zip format, the entry includes the Attached view, comments, camera position and 3D Cutting Planes (if any). (Regardless of the number of selected Markup Entries, they are all zipped into a single BCFzip file.) In the appearing dialog, give the file a name. Click the Export Selected Markup button.ģ. In the Markup Tools palette, select one or more Markup Entries.Ģ. Workflows for Using BCF in Project Markupġ. ![]() See IFC Global Unique Identifier Attribute (GlobalId). – When exporting an ARCHICAD project to IFC format, for use in a BCF workflow, make sure that you use the Translator export option to retain the elements’ Global IFC ID. BCF is used by many structural, MEP and model checker programs to add comments, screenshots, camera position and 3D cutting planes to IFC models. – BCF is an open standard format officially endorsed by buildingSMART. between architectural and structural elements). The markup entries will keep track of the elements referenced in the BCF file (with their IFC global unique identifier, IFC GlobalId), even through multiple exchange cycles.īCF-based data exchange is particularly suited for marking changes or collisions (e.g. After adding your own Markup changes, you can export it again as a BCF file. Use this feature to import and export Markups in BCF format when exchanging a model in IFC.įrom ARCHICAD’s Markup Palette, you can import a BCF (BIM Collaboration Format) file, whose contents are converted into Markup Entries in ARCHICAD.
