= Parallel mode =
[[JOSMImage(mapmode/parallel,middle)]] ''Shortcut key:'' **{{{Shift+P}}} ([ExpertMode expert mode] only)**

Creates a parallel copy of a way sequence while preserving its radian.


== Usage ==

1. Enter the Parallel mode by shortcut key {{{Shift+P}}} or in the [wikitr:/Help/EditToolbar#Workingmode Edit toolbar].\\
  The cursor icon changes to [[JOSMImage(cursor/modifier/parallel,middle)]].
1. Select the way which should be copied.\\
  To add more ways to the sequence hold `Shift` while selecting them with the [[JOSMImage(cursor/modifier/parallel_add,middle)]] mouse. 
  To drop a way out of the sequence use `Ctrl`. 
  The way sequence must be [wikitr:/Help/Action/SelectNonBranchingWaySequences branchless].
1. Drag to copy and to move the copy to the desired position. 
1. Release the left mouse button.

=== Modifiers ===
  * `Alt` to create a fresh objects without the tags of the source ways and their nodes. Hold before dragging.
  * `Ctrl` to override the snapping steps for the copy. Hold while dragging.

Normally the copy moves stepwise and cannot be dragged freely. 
It snaps in at each multiple of a predefined distance. 
The default step width is 0.50 m on a Metric system.

=== Other uses ===

Could be used to draw rough stubs: doughnut-like building, pedestrian plazas in parks, mazes, parking, possibly retail outlets or other areas with highly nested objects/infrastructure.

Pedestrian plazas and fountains have similar patterns. Many barriers, hedges and walls are also placed in parallel to each other.
