Provides access to members that construct domain extents based on defined precision. Note: the IConstructDomainExtent interface has been superseded byIConstructDomainExtent2. Please consider using the more recent version.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

 |
ConstructDomainExtent | Constructs a new envelope by expanding the input envelope about its center. Scale is typically a power of 10 indicating the number of sig figs to preserve. If its zero, the extent is expanded 1.5 times (subject to some constraints). |
|
ConstructZMDomainExtent | (deprecated, use ConstructZMDomainExtent2) Constructs a low precision Z or M domain extent centered on the specified extent. scale is 1/(desired resolution). If scale is 0.0, a default of 1,000,000.0 is used. |

| GeometryEnvironment | Provides a way of creating geometries from different inputs and setting/getting global variables for controlling behavior of geometry methods. |
Remarks
The methods on this interface are typically used to define domain extents for data sources that cannot persist that information. For example, the domain extent of a shapefile is determined as follows: The XY domain extent is the square enclosing the horizon of the shapefile's spatial reference. If geometries in the shapefile have M or Z attributes, then the current minimum and maximum values for those attributes are used to construct corresponding domain extents.
