Bentley MicroStation GeoGraphics Writer Parameters

Database Connection

ClosedDatabase Type

Select ODBC, Access MDB or Oracle.

ClosedAccess MDB File (available on Windows only)

Specify the path and filename of the Access database file to write.

ClosedAccess MDB Version

Sets the version of the output Microsoft Access file. Access file versions 97 and 2000 are the supported types. By default, an Access 2000 file is created.

ClosedODBC Data Source (available on Windows only)

Enter the ODBC data source that points to your MGE database. Depending on your database, you may also have to enter a username and password.

Tip: If you have installed ODBC drivers (which usually happens when you install Microsoft Access or another database), you can set up ODBC datasources using the ODBC option in your Windows Control Panel.

ClosedOracle Service Name (available on Windows and Linux only)

Enter the name of the Oracle service.

ClosedUsername and Password

Enter the username and password to access the service.

General Table Names

ClosedFeature

Specifies the name of the feature table to be written. This defaults to the name feature.

ClosedCategory

Specifies the name of the category table to be written. This defaults to the name category.

Design File Parameters

ClosedAllow Area Fills

Controls whether or not fill linkages will be written out for ellipses, shapes, and solids.

ClosedCompute Optimal Seed File Parameters

Select this option to automatically adjust the origin and scaling of the seed file to provide an optimum set of parameters for the input data.

ClosedOutput Units

Specifies how FME feature coordinates are interpreted and converted into Units of Resolution (UORs).

  • Master: UORs are converted into master units.
  • Sub: UORs are converted into subunits.
  • UOR: UORs are written as raw UOR coordinates.
ClosedTwo Point Line Output

Specifies how you want to store the two-point line features.

  • Type 3 Elements: Two-point line features are stored as type 3 line elements.
  • Type 4 Elements: Two-point line features are stored as type 4 line elements.
ClosedSeed File (V8 only)

Set the location of the seed file, which controls whether or not the output file is two-dimensional or three-dimensional, and sets the models, the global origin, and the unit information of the destination file.

ClosedCell Library File

The file name of IGDS cell library, which contains the definitions of cells which may later be output.

Write Optimization

ClosedFeatures Per Transaction

This parameter determines how many features are pushed to the remote server at a time.

Setting a high value for the transaction size can result in increased performance, since there can be significant overhead associated with each network request.

The default is 1.

ClosedImmediate Writes

Selecting this parameter instructs FME to immediately write each row of data to the database, rather than batching up writes into bulk arrays. Bulk arrays are normally preferred, as they require fewer trips to the database in order to store the data, but are not supported by some databases. (In particular, some ODBC drivers, such as the Excel driver, do not support bulk array loading.)
