Trimble SketchUp Writer Parameters

Entity Handling

  • Yes – Instructs the writer to merge coplanar faces with shared edges into a single face. Coplanar faces that overlap or do not share edges will not be merged.
  • No (default) – Coplanar faces will not be merged.

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):

For more information, see the links below:
  • Yes (default) – Instructs the writer to reproject features into a local coordinate system. If any of the input features do not have an associated coordinate system, reprojection will be disabled.
  • No – Reprojection will not occur.

File Content

Each value represents a version number. The SketchUp Writer will write the SketchUp model under the selected version.

The default is Trimble Version 2021.

Consolidating appearances can improve processing time for workspaces that contain a large number of appearances.

Although the default is set to Yes, there may be cases where a workflow requires that appearances not be consolidated (for instance, if subsequent processing requires separate appearances, or if each appearance has different texture parameters [for example, offset, scaling, etc.]).

Appearances that have the same raster reference, diffuse color, and alpha will be consolidated. Any other differences may be lost during consolidation.
