ArchiCAD elements created out of imported IFC model elements display their standard and custom IFC data, at the element level, in their respective Settings dialog boxes (Tags and Categories panel).
Note: Imported IFC elements and their properties (depending on the translator used) generally (by default) are protected against modification in accordance with the Reference model concept. Of course, by activating the layers of those elements, those elements too can be modified as needed.
In Element Settings, you can manage (define and edit) IFC data (Attributes, standard and custom Properties and Classification References) for searching (Find & Select), scheduling, labeling and IFC model export purposes. New IFC data can be added to the related elements manually or automatically, based on predefined rules in the Manage IFC Properties dialog. The interface of the Manage IFC Properties and its all functions are the same as the right side of the IFC Manager dialog box.
For detailed function descriptions, see IFC Manager and the sections which follow.
See Creating and Editing IFC Data.
Note: The available standard IFC Attribute and Property data types depend on the element’s “Element Classification” value. For example, if an ArchiCAD Wall element is classified as “ArchiCAD Type”, then its IFC Type will be (depending on its geometry) either an IfcWallStandardCase (e.g. straight wall), or an IfcWall (e.g. slanted wall). Only those standard IFC data sets will be available which correspond to the IFC Type (e.g. the Pset_WallCommon Property Set). If its classification is “Column”, for example, then the IFC standard properties corresponding to IfcColumn will be available (e.g. the Pset_ColumnCommon properties).
The new data - with their values, or else just the checked items without values - will appear under IFC Properties. Here, you can assign values to the available data fields that are still empty.
