How can I snap a vertex in a polyline/polygon to an existing point?

There is not a way to snap a vertex in a polyline or polygon to a point, but you can edit the coordinates of any vertex in the polyline/polygon to match those of the point using the Coordinate Manager.

To do this:

  1. Select the point and write down the exact coordinates for that point, as seen in the Coordinate Manager.
  2. Then select the polyline or polygon. The coordinates for all the vertices will be displayed in the Coordinate Manager.
  3. Click on one set of coordinates. The vertex that corresponds to those coordinates will be highlighted in green on the polyline or polygon.
  4. Use the arrow keys on the keyboard to scroll up/down in the Coordinate Manager until the vertex you want is selected.
  5. Change the coordinates for that vertex by highlighting the X or Y values in the Coordinate Manager and typing in new values.
