Polygon Data Fields (InfoWorks)

Polygon data can be edited on the Polygons Grid Window of the Polygons Grid or the Polygon Property Sheet.

Most data can be edited on the grid, but some fields cannot be displayed in the grid format.

To view and edit all polygon data, use the Property Sheet.

The following table describes all the data required to define a polygon.
