Drawing shapes

Choose Edit map first, then open the Draw tab.

The drawing tools

Tool	Shortcut	Use it for
Add pin	Ctrl+M	One place: an RVP, a hydrant, a casualty clearing station.
Draw line	Ctrl+L	Hose lines, road closures, the way in.
Draw area	Ctrl+P	Flood extents, sectors, search areas, building footprints.
Draw cordon		A circle of a set radius around a point.
Draw along roads		A line that follows the roads between the points you click. Only on maps with routing turned on.

On a Mac, use Cmd in place of Ctrl.

While a tool is on, a dark bar at the top of the map says what you’re drawing, how many points it has and how long or large it is so far.

Draw a line or an area

1. Pick Draw line or Draw area.
2. Click the map for each point.
3. To finish, click the last point again, or choose Finish shape in the bar.
4. Give it a name and a style in the panel that opens.

Press Esc or choose Stop to put the tool down.

To draw several shapes of the same kind in a row, turn on Keep tool active under Draw › Options: the tool starts again after each shape.

Make shapes meet exactly

To start or end on another shape, line a building footprint up with its neighbour, or follow a sector boundary, turn on Snap in the bar at the top of the map (or Draw › Options › Snap to features). See Snapping and shared edges.

Change a shape

Click a shape to select it, then:

• Move a point: drag it.
• Add a point: drag the small marker halfway along an edge.
• Delete a point: Alt+click it.
• Carry on a line from either end: Ctrl+click its first or last point.

Note

Snapping works when you drag points too, but following a shared edge only happens while you’re drawing. See what snapping doesn’t do.
