1FME ® Workbench Transformers Quick-Reference Booklet1 3DThese transformers create and modify three-dimensional surface and solid geometries.1 calculatorsThese transformers calculate a value and supply it to a new attribute on a feature. 3 collEctorsThese transformers operate on collections of features at the same time. The collection of features may be replaced by new features based upon them, have their attributes or geometries merged, or have their orders altered.4 DatabasEThese transformers allow interaction with external databases. Data can be extracted from databases and merged into the feature stream or merged onto features. Arbitrary SQL statements can also be executed.5 filtErsThese transformers perform tests on feature geometry and/or attributes, and allow the feature to be routed to different destinations depending on the outcome of the test.6 gEomEtric opEratorsThese transformers operate on thegeometry of individual features or groups of features.10 infrastructurEThese transformers provide interaction with the underlying FME translation engine facilities. These include functionality to log features, set feature colors, createindividual features and grids of features from nothing, and invoke the FME Viewer on features flowing by.12 linEar rEfErEncingThese transformers work with linear referencing data structures on FME features.12 listsThese transformers operate on FME attribute lists.13 manipulatorsThese transformers modify (manipulate) the geometry or attributes of individual features in isolation from other features. 19 rastErsThese transformers create, use, and output rasters. They operate on data consisting of a regularly spaced grid of values. 22 stringsThese transformers operate on character strings held in FME attributes.23 surfacEsThese transformers create, use, and output surfaces. They operate on data thatdefines a surface through the z coordinate, and then either outputs this surface in a variety of ways or applies the surface to other data.24 WEb sErVicEsThese transformers access web services using the HTTP protocol.25 WorKfloWThese transformers run workspaces either locally or on an FME server.25 XmlThese transformers work with XML data by mapping XML elements into FME features, using stylesheets to convert XML documents, and querying collections of XML data.fmE ® Workbench transformers Quick-reference bookletThis booklet contains a high-level summary of each transformer’s functionality. For detailed information, please visit or select FME Transformers from the Workbench Help menu.2Properties buttonWhat is a transformer?A transformer is an FME Workbench object that carries out the restructuring of features. FME contains over 300 different transformers to carry out different types of restructuring. In the Workbench interface, transformers are stored in the Transformer Gallery, and grouped in categories applicable to their associated functionality.common Elements used in transformer parameter DialogsEvery transformer has a Properties button on the right of the transformer.When you click the Properties button, most transformers display an Edit Parameters dialog. The content of this dialog depends on the transformer, and sometimes even on connections to the transformer. Most transformers have some common user interface elements, however, and those are described here.The Properties button at the top-right of the transformer is color-coded to show the status of the settings. If the Properties button is the same color as the transformer, you can use the transformer with its existing parameters.A yellow Properties button indicates that the transformer contains default settings, but you have not yet accepted them. You can use the transformer in this state, but the workspace results may be unpredictable.A red Properties button means that there is at least one parameter for which FME cannot supply a default value. You must provide a value in the required field(s) before the transformer can be used.When you click a Properties button, the Edit Parameters dialog that appears will usuallyhave some of the common elements shown in this example.You can edit the default transformer name.Required fields are highlighted. If this field is not filled in, the OK button at the bottom of the dialog is disabled.Click OK to accept changes and close the dialog. Note that this button is disabled if required fields have not been populated.The Defaults menu allows you to replace FME defaults for thistransformer with your own parameter defaults. You can always reset the dialog to FME defaults.Click this Help button to open the FME Workbench Transformer helptopic.Replaces the geometry of a feature that has CSG.Creates long, surface or solidgeometries with a fixed cross-sectional profile taken from theoriginal geometry of the feature.Replaces the geometry of a feature from donut or polygon to face.These transformers calculate a value and supply it to a new attribute on a feature.1 FME® Workbench Transformers Quick-Reference BookletConverts an attribute’s value from one numeric system (base) to another,Extracts the minimum and maximum values of the feature’s coordinatesinto new attributes.2Combines feature attributes.Creates bounding boxes for groups of features.
