Usage

Basic usage

Click on a way segment and drag it. There are up to 3 possible directions - at right angle to the original position and along its neighboring segments. The chosen reference segment will be indicated.

Note: In certain cases new nodes will not be created. Specifically, if new segment is just lengthening of the old one. However, the node will not be moved when it's part of another way, as to not affect the other way.

Tip: If you start with just a single line segment, you will get a rectangle.

Insert node

A double click at a way segment inserts a new node.

Move node

Click on a node and drag it along one segment. Possible directions are directions of all way segments connected to the node.

Modifiers

Shift

Always create nodes, even if new segment is just lengthening of the old one.

Alt

Don't alter original way, create new way instead. Ways will share the two nodes.

Ctrl

Move segment. Nodes are moved even if they are connected to other ways.
