Autodesk AutoCAD DWF Writer Parameters

Security

DWF files support an optional password for additional security. When specified, the file cannot be opened without the password.

Version

The format of the DWF file to be produced.

Supported values:

  • Compressed Binary (default)
  • Uncompressed Binary
  • ASCII

The version of the DWF file to be produced.

Supported values:

  • 4.2
  • 5.5 (default)
  • 6.0

The value corresponds with the release number of the DWF file that is produced.

Resolution

DWF file resolution can be determined at translation time in the form of the X Size and Y sizes, specified in pixels.

Specifies the horizontal width of the output DWF file in pixels.

Specifies the vertical height of the output DWF file in pixels.

Miscellaneous Options

Prevents unused colors in the color map from being stored in the DWF file.

Stores invisible layers in the DWF file and the usual visible layers.

Sets the initial viewport of the DWF file to the entire extents instead of the last actively seen viewport.

Calculates a tight bounding area around the graphic elements of a drawing.

Prevents additional layer information from being stored in the DWF file.

Prevents named views from being stored in the DWF file.

Spatial

Coordinate systems may be extracted from input feature data sources, may come predefined with FME, or may be user-defined. FME allows different output and input coordinate systems, and performs the required coordinate conversions when necessary.

How FME Processes Coordinate Systems in the Workspace

If a coordinate system is specified in both the source format and the workspace, the coordinate system in the workspace is used. The coordinate system specified in the source format is not used, and a warning is logged. If a source coordinate system is not specified in the workspace and the format or system does not store coordinate system information, then the coordinate system is not set for the features that are read.

If a destination coordinate system is set and the feature has been tagged with a coordinate system, then a coordinate system conversion is performed to put the feature into the destination system. This happens right before the feature enters into the writer.

If the destination coordinate system was not set, then the features are written out in their original coordinate system.

If a destination coordinate system is set, but the source coordinate system was not specified in the workspace or stored in the source format, then no conversion is performed. The features are simply tagged with the output system name before being written to the output dataset.

For systems that know their coordinate system, the Coordinate System field will display Read from Source and FME will read the coordinate system from the source dataset. For most other input sources, the field will display Unknown (which simply means that FME will use default values). In most cases, the default value is all you'll need to perform the translation.

You can always choose to override the defaults and choose a new coordinate system. Select More Coordinate Systems from the drop-down menu to open the Coordinate System Gallery.

Changing a Reprojection

To perform a reprojection, FME typically uses the CS-MAP reprojection engine, which includes definitions for thousands of coordinate systems, with a large variety of projections, datums, ellipsoids, and units. However, GIS applications have slightly different algorithms for reprojecting data between different coordinate systems. To ensure that the data FME writes matches exactly to your existing data, you can use the reprojection engine from a different application.

Note  To use this feature, you must have a supported GIS application installed on your system (for example, Esri ArcGIS®).

To change the reprojection engine, Select Workspace Parameters > Spatial > Reprojection Engine. In the example shown, you can select Esri (but the selection here depends on your installed applications):
