I wanted to check if two line features intersect with each other, so I imported them into an dataset and built topology. But when I tried to validate the topology rule, I got an error warning which said: Validate Topology Failed. [error id: 138]
Although I got all intersections using alternative way, I still want to know what cause this error 138 and how to fix it, I can't find any answer among the Internet, if you know anything, please help me!
