How Drawing Files Are Exported to IFC When you export a drawing to IFC, a file is created with information you specify for project name, project number, location of the file, and any external references (xrefs). The IFC file structure at export is hierarchical with 4 defined levels as shown. Even though the IFC file structure is not visible in AutoCAD Architecture, it governs the files created when an IFC file is imported. For information about other methods of sharing drawings with external users, see "Sharing Drawings with AutoCAD Users" on page 119. Drawings with External References If you are exporting a file that contains xrefs, the drawing file is mapped to (Ifc)Site by default. The (Ifc)Site structure may contain building objects and site geometry as well as xrefs. You control which xrefs in the drawing file are exported and how they display. If you want xrefs to display as a distinct level within the IFC file, you can specify different identifying labels under IFC Structure in the Export to IFC dialog. Each user-specified label becomes an IfcBuildingStorey within the IFC file. You can specify the same identifier, such as Level (1), for multiple xrefs to combine the objects within those xrefs into one IfcBuildingStorey. The example shown above exports to the IFC file structure shown below. Exporting a Drawing with External References Use this procedure to export a drawing as an IFC file and include selected xrefs. The drawing for export must be active on your drawing screen. Xrefs contained in this drawing are listed in the tree view below the drawing name and are selected and mapped to Level (1) by default. For these xrefs, you can change the selection, change the identifying label or add new levels in the drop-down list, and add text as descriptive information about the file being exported.

How Drawing Files Are Exported to IFC

When you export a drawing to IFC, a file is created with information you specify for project name, project number,

location of the file, and any external references (xrefs).

The IFC file structure at export is hierarchical with 4 defined levels as shown.

Even though the IFC file structure is not visible in AutoCAD Architecture, it governs the files created when an IFC file

is imported.

For information about other methods of sharing drawings with external users, see

“

Sharing Drawings with AutoCAD

Users

”

on page 119.

Drawings with External References

If you are exporting a file that contains xrefs, the drawing file is mapped to (Ifc)Site by default. The (Ifc)Site structure

may contain building objects and site geometry as well as xrefs.

You control which xrefs in the drawing file are exported and how they display. If you want xrefs to display as a distinct

level within the IFC file, you can specify different identifying labels under IFC Structure in the Export to IFC dialog.

Each user-specified label becomes an IfcBuildingStorey within the IFC file. You can specify the same identifier, such as

Level (1), for multiple xrefs to combine the objects within those xrefs into one IfcBuildingStorey.

The example shown above exports to the IFC file structure shown below.

Exporting a Drawing with External References

Use this procedure to export a drawing as an IFC file and include selected xrefs. The drawing for export must be active

on your drawing screen.

Xrefs contained in this drawing are listed in the tree view below the drawing name and are selected and mapped to

Level (1) by default. For these xrefs, you can change the selection, change the identifying label or add new levels in

the drop-down list, and add text as descriptive information about the file being exported.
