= Parallel mode =
[[Image(source:trunk/images/mapmode/parallel.svg)]] ''Shortcut key:'' **{{{Shift+P}}}**

Creates a parallel copy of a path while preserving its radian.
Multiple connected ways can form the path.

Usage:

1. Activate the Parallel mode by shortcut key or in the [wikitr:/Help/EditToolbar#Workingmode Edit toolbar].\\
  The cursor icon changes to [[Image(source:josm/trunk/images/cursor/modifier/parallel.png)]].
1. Select the way which should be copied.\\
  To prolong the path hold `Shift` and select more ways with the [[Image(source:josm/trunk/images/cursor/modifier/parallel_add.png)]] cursor. 
  To shorten it use `Ctrl` [[Image(source:josm/trunk/images/cursor/modifier/parallel_remove.png)]]. 
  The path must be branchless.
1. Drag the copy to the desired position. 
1. Release the left mouse button.

Modifiers:
  * `Alt` to create a fresh object without the tags of the source ways and their nodes. Hold before dragging.
  * `Crtl` 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 stepping 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.
