Background:
OpenCities Map automatically creates geometric properties for recognized features. These properties are read-only and are described as Geometry_Perimeter, Geometry_Area, and Geometry_Length.
Queried spatial features are also assigned geometric properties which are described as Database_Perimeter, Database_Area and Database_Length. These values are calculated by the database.
Rounding - Labeling
Geometric properties can be used labeling where they can be rounded using the XFM Evaluator Expression XFM.Round. For example, the following will round Geometry_Area to two decimal places: [XFM.Round([Geometry_Area],2).
XFM.Round can also be used to round off database geometric properties.
Rounding - Analyze Result dialog
The decimal places shown in the Analyze Result for Geometry_Length and Geometry_Permimeter is driven by the accuracy of the working units of the design file.
The display of the decimal places for Geometery_Area, Database_Length, Database_Perimeter and Database_Area are not affected by this setting.
Rounding - Data Browser
The decimal places shown in the Data Browser can not be changed. This is true for both Geometry and Database properties.
