Description:
This command operates in two ways, as explained below.
From within the target file:When operating this command from within the
"target" (source) file, the file to be returned is "placed" in the source as
"live data" which may be modified freely like most other entities in the
source file (except placed entities). The scale of the returned file will be
the same as that of the "target" file and the origin will remain unchanged. If
the specified file to be returned does not exist, you will be informed, and
asked for another name.


From within the file to be returned:When operating from within the file to be
returned, the command copies the entire contents of the current model into the
target file. The target file is opened by the system, and the entities and
instances (placed objects) copied into it become part of the selection group
in the target file. If the specified target file does not exist, you are
informed, and asked if you want to create a new file under that name. If you
reply `n', you may specify another name. The original file is saved.
This command may be used to return entities previously extracted by the \extf
command to their original file.
The command allows you to merge two files containing separate parts of
a model. You may split the file again subsequently using the \extf command
(e.g., to check the main core of a highrise building against the various
floors).
Note that following this command you may have to resolve junctions between
walls created in the two separate files.
