Trimble SketchUp Reader Parameters

Entity Handling

  • 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.
Note  Layers that are not visible will still have a layer (feature type) exposed in the schema.
  • 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.

Note  This parameter is ignored if you are writing to formats that support only UV coordinates.

Coordinate System

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.

Note  If the chosen datum is not valid, the default of WGS84 will be used.

Move to World Coordinate System

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.*.

Schema Attributes

Additional Attributes to Expose

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.
 

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.

Note  If all four coordinates of the search envelope are left at 0, the search envelope will be disabled even if this option is checked.

Search Envelope Coordinate System

Specifies the coordinate system of the search envelope if it is different than the coordinate system of the data. The coordinate system associated with the data to be read must always be set if this parameter is set.

If this parameter is set, the minimum and maximum points of the search envelope are reprojected from the Search Envelope Coordinate System to the reader’s coordinate system prior to applying the envelope.

Clip to Search Envelope

The underlying function for Use Search Envelope is an intersection; however, when Clip to Search Envelope is checked, a clipping operation is also performed.

  • When left unchecked (set to No), features that overlap the boundary will be included in their full (unclipped) form.
  • When checked (set to Yes), this option instructs FME to clip features to the exact envelope boundary. FME removes any portions of imported features being read that are outside the search envelope.

Clip to Search Envelope: No

Clip to Search Envelope: Yes

Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.

Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read.

The search envelope includes the bounding box and the extent of the raster.

The search envelope includes only the area within the bounding box.

The raster size will still match the bounding box, but the area without data will be filled with Nodata values to represent the absence of data, if the source raster has them.

Raster Nodata may be a single value across all bands, a single value per band, or a separate alpha or transparency band that indicates the lack of data values (this is more common in images than other types of rasters).
