Feature Builder window
The Feature Builder window allows you to define coordinates, view output coordinates, create geometries, calculate values, and view geometry metadata. The two main sections of the Feature Builder window are the Coordinates area and the Functions area. The Coordinates area contains information about the coordinates that are both input and output for a function. Once features are created, you can also view the coordinates for vertices on geometries. The Functions area contains the functions that can be executed in the selected library and the input and output parameters for each function. Once geometries have been generated using functions, they can be selected, and the metadata for their components can be viewed.
There is also a toolbar at the top of the window that contains tools so you can execute functions, queue coordinates, work with the scratch database, and open the Feature Builder Settings dialog box.
Tools on the Feature Builder window
The tools at the top of the Feature Builder window are as follows:
- The Execute tool
runs a function once all the coordinates and parameters have been defined. - The Toggle Queuing tool
toggles the ability to use output coordinates as the input coordinates for the next function. - The Clears The Input Coordinates tool
deletes the coordinates you have defined on the Input tab in the Coordinates area of the Feature Builder window. - The Clear Scratch Dataset tool
clears the features in the feature builder scratch dataset. - The Add Scratch Data Layers tool
adds the layers in the scratch database to the table of contents. Adding the scratch database layers allows you to see the geometries you have created. - The Settings tool
opens the Feature Builder Settings dialog box, which contains all the properties that can be configured for the feature builder.
The Coordinates area
The tabs in the Coordinates area display coordinates information related to geometries that are created, values that have been calculated, and vertices for geometries that are selected. The format of the coordinates can be managed on the Coordinates Display pane on the Feature Builder Settings dialog box.

The Input tab
The Input tab in the Coordinates area contains the points necessary to generate a geometry or calculate a value. In some cases, the function determines the number of coordinates that need to be defined. Others can have several coordinates defined, such as the polyline and polygon functions.
The Output tab
The Output tab contains the coordinates that are the result of a function. This can be the end point for a bearing distance, for example.
Vertices tab
The Vertices tab in the Coordinates area displays coordinates for all the vertices in a selected geometry.
The Functions area
The Functions area contains two sets of tabs. The first set contains a tab that lists the functions that can be executed from a library and another that allows you to view the components of a selected geometry that has been created using a function. The Functions tab lists the functions that can be executed, which determine the parameters displayed on the Input and Output tabs beneath it. The Components tab displays the metadata for an output geometry that has been selected.
The second set of tabs contains the input and output parameters and values for a function. The Input tab contains the parameters that must be defined before a function can be executed as well as any optional parameters that can be defined. The Output tab contains any parameters that are calculated as a result of the function.
Functions tab
The Functions tab in the Functions area lists all the functions available in a function library. The list can vary depending on the library you have selected on the Feature Builder Settings dialog box.
Input tab
The Input tab in the Functions area contains both required and optional parameters for generating geometries and calculating values. Required parameters include the azimuth, radius, buffer, and distance. Optional parameters include the magnetic variation value, source, and year.
Output tab
The Output tab in the Functions area contains values from a function. The output can be azimuths and distances.
Components tab
The Components tab in the Functions area lists components and related metadata. The features are listed according to their geometry types. The metadata includes the programmatic name of the function used to create the geometry, the source properties, and other metadata associated with the feature builder, such as the name and label.
The spatial libraries
The spatial libraries are groups of functions that allow you to create geometries as well as calculate distance and angle values. There are three spatial libraries with the feature builder:
- Geodetic Spatial Library—Contains functions that allow you to generate geometries or identify relationships using geodetic distances (that is, ellipsoidal) and directions.
- Cartesian Spatial Library—Contains functions that allow you to generate geometries based on distances and directions relative to a projected coordinate system.
- Compsys Spatial Library—Contains functions that allow you to generate geometries or identify relationships using geodetic distances (ellipsoidal) and directions. This library requires that you install the Compsys21 software available from the Federal Aviation Administration (FAA).

There are several functions available in the three feature builder spatial libraries. Below are descriptions of each function and the names of the libraries that include them.
