Snap Tool

The Snap function allows the pointer to snap to features (points, vertices, or line segments) of the selected layer, resulting in more precise measurements.

To use the Snap tool:

1. Enable the Snap option.

2. Select the layer to which measurement vertices should snap.

When the pointer approaches a point, vertex, or line segment of the selected layer, it automatically snaps to that feature. Click to define the vertex of your measurement.
