I have converted data from Microstation to ArcGIS. The converted data has undershoots at intersections, so I tried to snap lines using Spatial Adjusment. I've added some control points but ArcMap didn't fix them.

How can I fix the undershoots automatically? I have many lines in my data, and fixing them manually would be too time consuming.

    It looks like you are wanting to fix undershoots (and probably overshoots too) which is a different topic to spatial adjustment. Try using those terms to find suitable instructions.

If you have access to an ArcEditor (Standard) or ArcInfo (Advanced) license of ArcGIS Desktop there is a tutorial available on Using geodatabase topology to fix line errors such as undershoots and overshoots.

Unfortunately, the options for ArcView (Basic) are more manual and will involve extending lines and or trimming lines.


I think ET Geowizards has a tool if you do not have the licenses above but topology is the way to go if you do.

A possible workaround if they are all about the same length would be to create a feature class with a tolerance above the specified margin and load the data into the feature class.
