Combines polylines, which share a pseudo node, based on user specified attributes. The resulting polyline data set does not contain multi-part polylines. The topology of the data set is preserved. The function works like the UNSPLIT command of ArcEdit. The attribute update rules include range values update

Notes:
Example:
Input Layer |
After Dissolve: |
![]() ![]() |
![]() The topology is destroyed no node in the intersection point of the two streets |
After Clean Pseudo Nodes: Update rules: L_F_ADD Address Range Paired field L_T_ADD |
|
![]() ![]() Preserved topology. Address ranges updated correctly |
