Draw Nodes

source:/trunk/images/mapmode/node/autonode.png Keyboard shortcut: either A or N TOC(inline)

This tool behaves differently depending on how you use it.

Standard Mode

  • If you click on a blank area of the screen you add a new node independent of any existing way.
  • If you select an end node of a way and then click on a blank area of the screen you add a new node to the end of the existing way.
  • If no node is previously selected and you click between (or very close to) two nodes in an existing way the new node is added on the existing way, between two existing nodes. If two ways cross, and there currently is no node in common at the junction, and you click near the intersection of the two ways, then the node will be inserted into both ways, which will then share a common point.
  • If a node is previously selected and you click between two nodes in an existing way the new node is added on the existing way, between two existing nodes, and a way is drawn between the previously selected node and the new node.
  • If you click near an existing node it draws a "segment" between what was previously selected and the existing node, and this allows you to re-use existing nodes to make a new way / area (so that certain nodes and "segments" can be reused in more than one way/ area).

Alt modifier

If you hold down the Alt key when using this tool it starts a new way, rather than continuing an existing way.

Shift modifier

If you hold down the Shift key whilst using this tool it disables the "auto-connect" feature. So segments will not be drawn between new nodes.

Ctrl modifier

If you hold down the Ctrl key whilst using this tool it disables the snapping to an existing way, allowing you to draw nodes close to, but not part of an existing way.

Note

There is another way to add nodes.

When you zoom in to higher resolutions you will note that on a way, between a pair of nodes, there is a + symbol. If you drag this with the mouse it automatically becomes a new node. Using this method it is very easy to modify an existing way.

Angle snapping

You can choose the direction of next segment to make specific angle between segments (0,30,45,90, degrees etc.). To enable this mode press Tab and see helper lines while moving mouse. To fix the direction and move mouse far from snapping line, please hold Tab key. Right click on any way segment when snapping is on and draw next segment parallel to it.

To choose angles, disable showing helper geometry, or disable snapping, use right-click on Angle symbol in statusbar and select corresponding item in popup menu.
