Tidy Coincident
Overlapping Lines
Determines how the new entities are produced where entities partially overlap.
Merge overlapping lines
If this option is selected Impact will create a single entity covering the full length of the overlapping entities.
Remove overlapping section
If this option is selected Impact will create separate entities for each overlapping section. So, a pair of overlapping lines will result in three separate sections.
Bridge
Determines how to bridge the new entities.
Retain Positions
If this option is selected bridge positions will be the same as the result of the overlapping entities.
Rebridge entities
If this option is selected each new entity will be rebridged according to its palette attributes.
Merge bridges
If this option is selected the bridges from all the overlapping entities will be added to the new entities.
The pictures below show examples of the different Bridge options:
Before (entities separated for clarity)
Bridges - Retain bridge positions
Bridges - Rebridge entities
Bridge - Merge bridges
Merge end to end Lines
If this option is checked then all end to end lines of the same palette will be merged into a single entity.
Look Within Blocks
If this option is checked, then the entities within a sub-block will be checked for overlapping entities. If this option is not checked, the search only covers entities in the top level block.
Tolerance
This is the distance between parallel entities that will be treated as overlapping.
