Why can't arcgis select a rectangular area but an entire area?
There is a problem with ArcGIS's toolbox. The ArcGIS product line provides users with an extensible and comprehensive GIS platform. Arcgis can't select the rectangular area because there is a problem with the ArcGIS toolbox, so it is recommended to restart. ArcObjects contains many programmable components, ranging from fine-grained objects (such as a single geometric object) to coarse-grained objects (such as map objects interacting with existing ArcMap documents), which integrate comprehensive GIS functions for developers.
