 = Create Areas By Extrusion =

-Replaces the section of a Way between two nodes and replaces it with three line segments, one of which is parallel to the original, and two at right angles (which also requires two additional nodes).
+Replaces the segment of a [[Image(source:trunk/images/data/way.png)]] [Help/Concepts/Object#Ways way] between two [[Image(source:trunk/images/data/node.png)]] [Help/Concepts/Object#Nodes nodes] with up to three way segments, one of which is parallel to the original.
 
-Press the "Create Areas" mode button (or the {{{X}}} shortcut), then drag a line segment. It will move at right angles to its original position, connecting to it with two additional segments.

- * If you start with just a single line segment, you will get a rectangle.
- * If you start with an area, you will tack on a rectangular protrusion to the area.
+== Usage ==
 
-Hold down the ''Alt'' key and drag a line segment to create a new rectangle and leave the original rectangle intact.
+=== Basic usage ===
 
-A double click at a line segment inserts a new point.
+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.
+
+[[Image(BasicExtrudes.png)]]
+
+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.
+
+[[Image(MoveNode.png)]]
+
+== Modifiers ==
+
+=== Shift ===
+
+[[Image(source:trunk/images/cursor/modifier/rectangle_plussmall.png)]] Always create nodes, even if new segment is just lengthening of the old one.
+
+[[Image(Shift.png)]]
+
+=== Alt ===
+
+[[Image(source:trunk/images/cursor/modifier/rectangle_plus.png)]] Don't alter original way, create new way instead. Ways will share the two nodes.
+
+[[Image(Alt.png)]]
+
+=== Ctrl ===
+
+[[Image(source:trunk/images/cursor/modifier/rectangle_move.png)]] Move segment. Nodes are moved even if they are connected to other ways.
+
+[[Image(Ctrl.png)]]
+
+== Customization ==
+
+* Colour of main line: Defaults to {{{selected}}} colour, but can be changed with [Help/Preferences/Advanced advanced preference] {{{color.extrude.main.line}}}.
+* Stroke of main line: {{{extrude.stroke.main}}}. Parameters: {{{<width>}}} for solid line (width in pixels), {{{<width> <dashlength> <spacelength>}}} for dashed line.
+* Stroke of old line (used while [#Ctrl moving segment]): {{{extrude.ctrl.stroke.old-line}}} (stroke parameters).
+* Colour of helper line: {{{Extrude: helper line}}} in [Help/Preferences/Display#Colours colours settings].
+* Stroke of helper line: {{{extrude.stroke.helper-line}}} (stroke parameters).
+* Size of right angle helper symbol: {{{extrude.angle-symbol-radius}}} (pixels).
