Trimble SketchUp Reader Parameters

• Yes – Forces all edges to be read in.
• Auto – The value of the SketchUp option View: Edge Style will determine whether edges are read in. This option is stored on the feature as the attribute RenderingOptions.EdgeDisplayMode.
• Standalone Only – Only edges that do not make up faces will be read in.
• No (default) – Edges will not be read in.

• Yes – Instructs the reader to read all geometry elements, even if they are not displayed inside the SketchUp application. Geometry can be hidden with the visibility flag on the layer or on individual geometry elements
• Auto (default) – The value of the SketchUp option View: Hidden Geometry will determine whether invisible Geometry and Layers are read in. This option is stored on the feature as the attribute RenderingOptions.DrawHidden.
• No – Only geometry elements that are visible will be read in.

• Yes – This option instructs the reader to use the material associated with a geometry’s layer when creating its appearance. This option can be useful to visualize which layer each geometry is associated with. Entities associated with Layer 0 that are nested within a group will inherit that group’s layer material.
• Auto (default) – The value of the SketchUp option Color by Layer will determine whether to use layer materials. This option is stored on the feature as the attribute RenderingOptions.DisplayColorByLayer.
• No – Appearances will be created using the material associated with each geometry.

Controls whether or not to read textures on the geometry.

By default, this parameter is set to Yes.

Outputs SketchUp textures with full UVQ texture coordinates.

By default, this parameter is set to Yes.

Use this parameter to expose Format Attributes in FME Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario, this parameter allows you to expose additional attributes on multiple feature types. Click the browse button to view the available format attributes (which are different for each format) for the reader.

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.

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.

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):

This parameter selects the datum that will be used to define the coordinate system of the SketchUp model. A datum can be chosen from the list, or entered manually.

Yes – The companion dataset files (having the same name as the primary file) are read in order to acquire the coordinate system and the data necessary to convert points to the world coordinate system. If there are no companion files with the same name as the primary file, FME looks in the same folder for files named global.*.

A search envelope (also known as a bounding box) is a rectangular area that defines a geographic area. In FME, the easiest way to define a search envelope is to use search envelope parameters.

Defining a search envelope is the most efficient method of selecting an area of interest because FME will read only the data that is necessary – it does not have to read an entire dataset. Search Envelope parameters apply to both vector and raster datasets and can be particularly efficient if the source format has a spatial index.

Most FME readers have parameters to define the search envelope of data that is being read:

The parameters include the x and y coordinates of the bounding box as well as a parameter that defines the coordinate system.

How to Define the Bounding Box

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned. Note that the bounding box intersection is not a full geometry intersection (based on spatial relationships) that would be returned by a transformer like the SpatialFilter.
