FAQ: When Using the Editor Toolbar Merge Command to Combine Overlapping/coincident Feature

Answer

If the X and Y values are the same (vertices are coincidental) but the Z values are different, the larger Z value is always used in the output vertex. See the example workflow below:

Segment 1 of overlapping line feature (note the Z values)


Segment 2 of overlapping line feature (note the Z values)


Merging these segments, choosing segment 1


Result keeps higher Z values


Merging these segments, choosing segment 2


Result keeps higher Z values
