Poly-Build Tool

The PolyBuild tool takes a group of spatial point objects and draws a polygon or polyline in a specific sort order to represent that group of points.

The most common use of this tool would be to create a Convex Hull polygon representation for a set of points. See the ConvexHull_TradeArea.yxmd from the Spatial Samples directory.

This tool can also be used for spatial layer development. A typical example where you would use this tool is if you had a collection of GPS data that you needed to translate into polygon or polyline objects. If you were mapping out a river, road, pipeline, reservoir or property boundary, for instance, this tool would be quite useful.

Configuration Properties

  1. Select the Build Method. Choices include:

  2. Depending on the Build mode chosen, the user will have to populate a series of drop down lists with the appropriate field name with respect to their data stream.


Polyline: A polyline contains multiple line segments, where a line has one start and one end point, but can have any number of points in between. A polyline can be quite complex as in the case of road systems, or rivers.

Polygon: A polygon is a simple bounded region. A region can be made up of many individual polygons, such as in the case of the state of Hawaii.
