A quick tour of feature builder

The Production Feature Builder toolbar and Feature Builder window allow you to create complex geodesic and ellipsoid features.

Production Feature Builder toolbar buttons and their functions

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 Coordinates area

The tabs in the Coordinates area all display coordinates information that is 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.

Input tab

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.

Output tab

Vertices tab

The Vertices tab in the Coordinates area displays coordinates for all the vertices in a selected geometry.

注意注意:

You must be in an edit session to populate the Vertices tab.

Vertices tab

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.

Functions tab

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.

Input tab

Output tab

The Output tab in the Functions area contains values from a function. The output can be azimuths and distances.

Output tab

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 feature builder such as the name and label.

Components tab

The function libraries

The function libraries are groups of functions that allow you to create geometries as well as calculate distance and angle values. There are three function libraries with feature builder:

The functions

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