By using closest facility, I found closest path between 78 points. Now, I am trying to split this route at intersection points by using feature to line management tool. However, I am getting a Topoengine error. What I tried to solve this problem is that :
1. I used repair geometry.
2. I used check geometry.
3. I unchecked background processing from geoprocessing option.
4. I copied the data to new file geodatabase.
But, I could not fix this problem. If you have any suggestion to me, I will be appreciated for that.
