Issues with Split Line at Point - Lines not splitting at all points

ATricomi — Thu, 27 Feb 2025 16:37:36 GMT

I have lines that need to be split wherever they intersect with a polygon boundary. I used the Intersect tool to create points at those intersections. Then I used the Split Line at Point tool. The problem is occurring only with lines that cross a polygon boundary twice. In these situations, the line will only split once, at one of the points, instead of at both points. Here is an example in the photo below. As you can see, the selected line was split at the point on the left, but not the point on the right. I have already used the Multipart to Singlepart tool to separate the intersection points but this did not resolve the issue.

If you run the above again, does it split?

The vague wording about specifying a search radius to get both points to intersect at once would be a stretch given the interpoint distance between the intersecting points in your example.

Another thread suggested copying the inputs into a new projected gdb

I was able to solve the issue by entering a 0.1 meter search radius in the tool. Thank you!

Strange, it seems that entering any search radius uses all points, not all the points within the search radius, hence it accepts points at either end of the line
