Enabling snapping

Snapping can be enabled on the Snapping toolbar.

Below are the available snap types and how you can use them.

• Point Snapping: snap to point features.
• End Snapping: snap to the start or end points of lines.
• Vertex Snapping: snap to the vertices of lines of polygons.
• Edge Snapping: snap to lines or polygon boundaries.
• Intersection Snapping: snap to the intersection of two or more line or polygon features.
• Midpoint Snapping: snap to the midpoint of line or polygon segments.
• Tangent Snapping: snap to the point of tangency on curved line or polygon segments. Note that you must have at least one vertex placed before you can snap to a tangent.
