Line Unification (LU) is a read-write cleanup action. It is designed to reduce the number of lines in a layer by eliminating redundant lines (replace pairs of lines with single lines wherever possible), without changing the design of the layer. The system preserves the correct overlap between touching features in order to avoid the generation of slivers.
LU operates on shapes of any layer. The associated drill and rout layers influence results of this action for board layers.
A new option was added to the Unify lines parameter in the Line Unification action screen: Broken Arcs .
The new option enables the action to look in the data for broken arcs and then try to unify them into one or more arcs. This reduces the number of lines in the data. An example:
