Getting Started with the Transformer Designer

To start a new transformer

1. Click New Transformer on the Start page, click New on the Toolbar, or from the menu, select File > New.
2. In the New Transformer dialog, provide the following:
   • Transformer Name: The name of the transformer.
   • Package Name: The name of the FME Package containing the functionality of the transformer.
   • Alternate Names: One or more names of the transformer to reference as aliases. Specify multiple names with a space. To enter names that are properly delineated, click the ellipsis (...). (You can edit this setting later when Configuring a Transformer.)
   • Categories: One or more categories to which the transformer belongs. Categories display in the FME Workbench Transformer Gallery and in FME Hub. Click the ellipsis (...) to select categories. (You can edit this setting later when Configuring a Transformer.)
3. Click OK. The Transformer Designer interface opens. Proceed to Configuring a Transformer.

To edit an existing transformer

Open a .fmx or .fmxj file from the recent files list on the Start page. Alternatively, drag and drop a file onto the Start page, click Open on the toolbar, or from the menu, select File > Open. If you open a .fmx file, you must agree to convert the file to a new .fmxj file before proceeding.

The file opens to the Transformer Designer interface. From here, you can proceed to:

• Configuring a Transformer
• Execution Instructions
• Working with Transformer Versions, Upgrades, and Change Logs

Saving a Transformer

The FME Transformer Designer creates .fmxj files, which capture the transformer interface and can be read by FME Workbench.

Refer to the Package project structure documentation in the FME Packages SDK Guide for details on where to store the .fmxj within an FME Package.

Click Save on the toolbar, or from the File menu, select Save or Save As.

Sharing a Transformer to a Shared Directory

You can save a transformer to a shared directory that is accessible from FME Workbench, outside of the package. This approach is useful if you want to test the transformer interface in FME Workbench before saving it with the package.

1. From the Tools menu, select FME Options > Default Paths.
2. Under Shared FME Folders, add your desired storage path. For more information, see Shared FME Folders.
3. Save the .fmxj file to the Transformers directory within the path.
4. In the FME Workbench Transformer Gallery, click the Reload button to force FME Workbench to update the fmxj file. The changes will only reflect on any new instances of transformers added in FME Workbench.
