000261: Cannot add point features to TIN.

Description

An intermediate TIN surface is created from the input points and is used to generate the output Thiessen polygons. A failure has occurred while attempting to add features to the intermediate TIN surface.

Solution

Check that the output workspace exists and is not read-only. If read-only, change the permissions to prevent write access problems. If the error persists, attempt setting the output to a different location.
