Problem: Clipping data at a projection horizon doesn't always work


Each projected coordinate system has a horizon, an area beyond which data isn't valid. At times, ArcMap does not clip geometries at the horizon's edge correctly. The clipping works correctly only the first time the coordinate system is used in a session.


This is a software limitation. The horizon and geometry domains are set incorrectly, which causes the intersection and difference results to be rejected.

Solution or Workaround

Restart ArcMap.
