With one or more ways selected, the form will be modified so that all angles will be 90 or 180 degrees.

Orthogonalization is not Rotation

Some users confuse this tool with rotation.

Orthogonalization is not Rotation.osm

before (note small extrusion, multiple times smaller than other part)

For rotation see Rotate.

Using two nodes for alignment

You can select two additional nodes. Then segments will be aligned in accordance with these nodes.

Later, you can cancel the movement of certain nodes, select them and press Shift+Q.

Complex buildings

  • use split buildings temporarily with P Split Way
  • orthogonalize portions of a building as usual
  • reconnect parts back with C Combine Ways

Select nodes you want to undo, then press Shift+Q and selected nodes will be placed back to origin.
