[[JOSMImage(ortho)]] ''ショートカットキー:'' **{{{Q}}}**

**全ての角が90度か180度になるようにノードを配置します。**

一つ以上のウェイを選択すると全ての角が90度か180度になるように変形されます。

[[JOSMImage(misc/error,20,middle)]] **Be careful when using this feature e.g. on buildings. A lot of buildings are indeed not orthogonal in reality.**

== Simple use case ==

Select each way separately or several ways together and hit `Q`. This will orthogonalize each single way on its own. Ways with min. 2 sharing nodes which were selected together were orthogonalized together too.

== Using two nodes for alignment ==

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

== Complex buildings == 

* temporarily split buildings with {{{P}}} [wikitr:/Help/Action/SplitWay Split Way]
* orthogonalize portions of a building as usual
* reconnect parts back with {{{C}}} [wikitr:/Help/Action/CombineWay Combine Ways]

== Undo moves of selected nodes ==

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

== Orthogonalization is not Rotation ==

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

After Orthogonalization ([https://knowledge.autodesk.com/support/autocad/getting-started/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-9810D35D-E975-49E2-88EA-51FE4ACC92DB-htm.html dimensions]/length is not preserved):

For rotation see [wikitr:/Help/Action/Select#Rotate Rotate].
