Enables / disables line, point and polygonal layers for snapping. New lines will be snapped to the closest line of selected layers.
- Prefer snapping to points
The function is enabled: The line is snapped to the closest point (figure 2). If there is not any point within the snapping distance (line vertex) the line is snapped perpendicularly to the nearest line (figure 4). Note: It is possible snap to the segments.
The function is disabled: The line is snapped to the closest line (figure 1 and 4).
- Snap to points only
