Only a currently active drawing can be exported to IFC. The export process generates 2 files:
- An IFC file that contains information specified for project number and name, file path, and external references (xrefs).
- A LOG file that contains data about information (objects and geographic location) in the drawing. This file is stored in the same location as the IFC file.
The current display configuration for the drawing being exported is what defines the graphical information and geometry for the IFC file. Objects that would typically display in the current display configuration are exported regardless of whether their layers are frozen or turned off.
You can export a property set as an IfcElementQuantity if an object with a property set definition has a suffix of IfcElementQuantity. The property set definition must also include at least one property name with a value, such as IfcQuantityArea, IfcQuantityCount, or IfcQuantityLength. This information displays on the Extended Data tab of the Properties palette. The IFC Quantity Information is only exported from AutoCAD Architecture 2022 toolset to the IFC file when the Quantity Add On option is selected in the Export Options dialog box.
You can use the property set definition template (IFC_Object_Attribute_Pset definition.dwg) to assign various sample IFC object attributes to objects. Attributes that are set directly by the IFC export process are not part of the definition. This template can be found in the following location: C:\ProgramData\Autodesk\ACA <version>\enu\Styles.
AEC tab. Spaces and their boundaries must be set to Associative if you want to export space boundary information. For best results, use Associative Freeform Space to achieve air tightness in a model. When there is a virtual boundary—a boundary between spaces or a space with nothing in it—draw a line along the expected boundary, and set Bound spaces as Yes. This space will be exported as a Virtual space boundary in IFC.
You can specify the geographic location of the project and the True North direction using the AutoCAD geographic location.
For AutoCAD MEP 2022 toolset, IFC Type Classifications are mapped to MvPart Objects (such as equipment, panels, and devices) automatically. This classification is added in the Autodesk Catalog Editor by default. You can modify this classification or add more classifications to the content library in the Autodesk Catalog Editor.
