By default, the <WriterKeyword> for the IGDS writer is IGDS, so a typical mapping file fragment configuring the IGDS writer would be:
IGDS_DATASET /usr/data/dgn/92b034.dgn
IGDS_SEED_FILE /usr/data/dgn/2dseed.dgn
IGDS_CELL_LIBRARY /usr/data/dgn/cartog.cel
DATASET
The file name of the output IGDS file.
Required/Optional
Required
Workbench Parameter
Destination Bentley MicroStation Design File
SEED_FILE
The file name of the Design file which will be used to seed the output file’s header information. The default seed file (V8) is:
$(FME_HOME)/design/seed3d_m_v8.dgn
To write to V7, you will have to select a valid V7 seed file.
It is important to note that the seed file determines which destination version to write.

An unsigned integer ratio
Required/Optional
Optional
Workbench Parameter

MANGLE_DBCS_TEXT
Controls whether or not double-byte-character-set text is mangled when text strings are written to Version 7 DGN files.
MicroStation uses special header bytes to single DBCS text. Note that the IGDS reader automatically de-mangles DBCS text.
Values
YES | NO (default)
If this directive is set to Yes in the mapping file, then these special bytes will be output when a DBCS text string is encountered. The default value is No.
Version
This directive applies to the V7 writer only.
Required/Optional
Optional
Workbench Parameter
Mangle DBCS Text (V7 only)
SPLIT_BIG_DGN7_FILES
Allows user to split Version 7 DGN files bigger than 32 MB.
Note that this directive can be manually set to No in the mapping file.
Values
YES (default) | NO
Version
This directive applies to the V7 writer only.
Required/Optional
Optional
Workbench Parameter

SPLIT_SIZE_DGN7_FILES
This directive allows you to set the size of the output file, in MB. It is applicable only if SPLIT_BIG_DGN7_FILES is set to YES.

SCALE_CELL_MODELS
If set, indicates that the coordinates of named cells written to the destination should be scaled from the coordinate space of the cell model to the coordinate space of the seed model (which is used as the destination). This affects shared and unshared cells, which do not have a cell size (i.e. igds_cell_size, or igds_cell_size_x and igds_cell_size_y) set. This behaviour is similar to the setting for True Scale when placing cells in Microstation.

This directive currently applies only to the V8 writer.
Required/Optional
Optional
Workbench Parameter
Scale Cells to Destination Model

This only applies to text features with RSC font IDs specified in the igds_font attribute, and which are found in the specified RSC file to be symbolic fonts. If this directive is not specified, text elements with symbolic RSC fonts will have their placement, size and range estimated.
