Adds z coordinates to features, creating or modifying 3D geometry.

Jump to Configuration

Typical Uses

  • Converting 2D geometry to 3D

  • Updating z coordinates with new values

How does it work?

The 3DForcer receives any geometry type and adds z coordinate values, converting 2D features to 3D.

Z values may be supplied by an attribute, expression, or user parameter. Existing z values may be preserved or overwritten. If a non-numeric value is provided, features will output via the <Rejected> port.

Z values should generally be in the same units as the x and y coordinates. Features with latitude/longitude coordinate systems may need to be reprojected.

Raster features, including digital elevation models, will pass through unchanged.


Usage Notes

  • This transformer applies the same z value to all vertices of a feature. To interpolate vertex elevation values from another dataset, use the SurfaceDraper.

  • To apply elevations from an underlying digital elevation model, use the PointOnRasterValueExtractor.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
