To access feature type parameters, click the gear icon 
on a feature type in the workspace to open the Feature Type Parameter Editor. To always display the editor in Workbench, you can select View > Windows > Parameter Editor.
General
All feature types share similar General parameters, including the Feature Type Name, Reader or Writer Name, and Geometry.
In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept a Table Qualifier prefix on the output table feature type.
See Editing Writer Feature Types for more information.
Shapefile Settings
This parameter applies at the feature type level. The initial value for this parameter is obtained at the writer level (see in the Shapefile writer parameters dialog), but it can also be modified for individual feature types.
Output Dimension
- Dimension from First Feature: Shapefiles produced will contain geometries with dimension information obtained by the first feature observed by the writer.
- 2D: Shapefiles produced will contain two-dimensional coordinate geometry.
- 2D + Measures: Shapefiles produced will contain two-dimensional coordinate geometry and measures.
- 3D + Measures: Shapefiles produced will contain three-dimensional coordinate geometry and measures.
