Parallel mode

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 Edit toolbar.
    The cursor icon changes to source:josm/trunk/images/cursor/modifier/parallel.png.
  2. Select the way which should be copied.
    To prolong the path hold Shift and select more ways with the source:josm/trunk/images/cursor/modifier/parallel_add.png cursor. To shorten it use Ctrl source:josm/trunk/images/cursor/modifier/parallel_remove.png. The path must be branchless.
  3. Drag the copy to the desired position.
  4. 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.
