Using the Key-in IFCOUT

The IFC Export tool key-in command syntax IFCOUT [FILENAME [OPTIONS]] makes use of combinations of switches and arguments.

The filename is either the IFC file path, or * to generate from the source DGN file name. If not specified, the Key-in opens the IFC Export dialog.

Options have both short and long forms. For instance, "c" or "cobie". Some options have arguments separated by a colon to control their operation. For instance, "m:FMH" or "mvd:FMH".

Tip: The OPTIONS portion of the key-in may be listed in any order:

Option	Action	Argument values
`c` [cobie]	Create COBie spreadsheet	no argument
`o` [optimize]	Optimize IFC file
`z` [zip]	Zip IFC file
`m` [mvd]	Specifies Model View Definition	One of the following: IFC2x3_EX - IFC2x3 CV2.0 + QTO & Space Boundaries (default) IFC2x3_CV – Pure IFC2x3 CV2.0 IFC2x3_FMH - IFC2x3 Facilities Management Handover IFC4_RV - IFC4 Reference View IFC4_DTV - FC4 Design Transfer View IFC4_DTV_BS - IFC4 DTV with NURBs
`t` [tolerance]	Specifies tolerance for facet approximation of curves and curved surfaces	Value from range 1000-5000 Default: 1000

Examples	Result and IFC Export equivalents
`Ifcout *`	Exports IFC2x3 CV2.0 + QTO & Space Boundaries to the file with the same name and name of dgn.
`ifcout * o`	Exports IFC2x3 CV2.0 + QTO & Space Boundaries to the file with the same name and name of dgn and optimize it.
`ifcout * m:IFC2x3_FMH c`	Exports IFC2x3 Facilities Management Handover and create COBie spreadsheet.
`ifcout * mvd:IFC2x3_FMH cobie optimize zip`	Long form version. Exports IFC2x3 Facilities Management Handover, optimize IFC file, and COBie spreadsheet and zip ifc file.
`ifcout c:\test.ifc [m:IFC4_RV \| IFC4_DTV \| IFC4_DTV_BS]`	Exports IFC4 Reference View \| Design Transfer View \| DTV with NURBs respectively, to the file c:\test.ifc.

Note: Key-ins and options can also be used when exporting IFC files in batch process.
