Configuration menu (Q)

Drawing

• Use left mouse button clicks or drags to create draft contour.
• Ctrl+Click adds fixed point that will not be affected by simplification; you may use it for corners or other significant parts of shape but this is not required.
• When dragging over existing nodes, they are included in new line automatically.
• Clicking on the first point makes the line closed (no more adding points).

Editing in drawing mode

• Backspace - delete last added node, then previous etc.
• Ctrl+Shift+Click - clears the sketch and start new one.
• Ctrl+Click on fixed node makes it free, Ctrl+Click on free node makes it fixed (see marks).
• Shift+Click - delete selected node (marked by red X) or selected fragment. Fragment is a line between two fixed nodes.
• After deletion of the fragment you can redraw it by mouse from the beginning to the end (active segment marked orange).
• To stop editing fragment Shift+Click on free area or press Escape.

Please use simplification and validator! Do not upload huge and self-intersecting lines.
