Elements will never be overwritten as a result of a merge. This means that if a merged element has the same IFC GlobalId Attribute as an existing element in the IFC file, then the element will be merged using a new IFC GlobalId Attribute. In case of Merge to IFC Model, the content of the existing IFC file is protected: merging a file to IFC will only add to it, without replacing any of its elements. There are many free IFC viewers on the market that can be readily downloaded, including: Hint: After exporting an IFC model, it is good practice to check the IFC model in an IFC viewer (or in ARCHICAD by reopening the IFC file).

Regardless of the method, the export process is controlled by an IFC Translator for Export, which defines how ARCHICAD elements should be interpreted and displayed in IFC. For each Publisher item, you can vary the Translator, so that the view content can be customized to the needs of the recipient, creating the desired output with a single click. Publisher ( Document menu): publishes views to any of the IFC file formats.For example, use this command if you want to add selected content from an ARCHICAD model to an IFC file from another discipline. Merge to IFC Model ( File > Interoperability > IFC): merges only certain elements or, alternatively, the entire content of the current ARCHICAD project into an existing (unopened) IFC file.Save as ( File menu): exports the entire current ARCHICAD project or just its filtered content to an entirely new IFC file.There are three export functions to choose from.
