Trying to split a line

CharlesEiseman — Thu, 27 Feb 2025 13:20:04 GMT

I am trying to split a line. I have selected the line, made sure that nothing else is selected, clicked "Modify," then "Split", then drawn a line across the point where I want the line to split. I keep getting a "splitting features failed" message when I double-click to end the line (or click "finish"). What am I doing wrong?

Hey @CharlesEiseman

I've heard that it sometimes it will work if you pass over it once more, so place point, cross line, and then snap back to first placed point. This shouldn't be a major fix if that works, but I believe this is related to a bug that I'll track down.

What version of ArcGIS Pro are you seeing this issue in?

What is the data source (enterprise (SDE) database, file gdb, other)?

How can I tell what version it is? I don't see any indication of that on my computer--it's the version I was forced to download in December when I renewed my license and was no longer allowed to access my ArcMap 10.8.2 software. So I imagine it's whatever the newest version is.

Oh, and the data source is a shapefile I created in ArcMap.

For the ArcGIS Pro version, click on the Project tab in upper left and then click on About near the bottom of the left side list and that tab will show you the version.

Can you try adding the shapefile data to a new file gdb created in ArcGIS Pro and then see if the Split tool works any better?

Okay, it's version 3.4.2.

How do I create a gdb and add shapefile data to it? I've been using ArcMap for 20 years, just learning the bare minimum I need to make simple maps, and I've never had a reason to deal with geodatabases...

Under View on top ribbon choose Catalog Pane

Databases should be an option in the Catalog Pane

Right click on Databases and select New File Geodatabase - name and save file gdb to appropriate location for project

In the Table of Contents right click on the layer in shapefile format

Go to Data then Export Features and populate the output feature class in the file gdb that you just created. You can keep the same layer name or give it a new name during this export process.

Click Ok and your data should now be in file gdb format, so you can test if Split works better with that data container.

@CharlesEiseman

can you confirm if the feature layer and the map have different coordinate systems? If so, Can you change the Map coordinate system to match that of the layer and and try spliting again?

To check layer's coordinate sytem, Right-click the layer in Contents pane, choose Properties then click Source tab, expand Spatial Reference group to reveal spatial reference information including coordinate system.

For the Map, Right-click the Map, choose Properties, then click the Coordinate Systems tab, the coordinate system information should be under Current XY. If this coordinate system is different from that of the layer, change it to match.
