Snap to Line Mode

Snap to Line Mode (under development)

Snaps the vertex to add to the closest point over a line segment
By selecting the Snap to Line button on the Modes Toolbar, you're instructing uDig to search for the closest point over a line segment the lies inside the Snap Area, each time you click over the map, and to add a vertex at that location.

Whether you can select snap to vertex from a Feature in the current Layer, in all Layers, or in the Grid, depends on the Snap Behaviour set as preference.

Figure 1 shows an example of using the Snap Area to snap to a segment in a Feature from another Layer.


Figure 1 Using Snap Area to search for the "snap to" segment

Once you click over the map and a segment that intersects the Snap Area is found, a new vertex will be added on the location over the segment found closest to the click point, as shown in Figure 2.

Tip

When using the Snap Area behaviour, remember you could adjust the size of the snap area with the mouse wheel while pressing the ALT key.
