Setting the snapping tolerance

The snapping tolerance is the distance within which the pointer or a feature snaps to another location. If the element being snapped to—such as a vertex or edge—is within the distance you set, the pointer automatically snaps to the location. You set the default snap tolerance value in pixels.

For example, to make a new electric utility line snap to an existing electric line's end, first make sure end snapping is enabled (in other words, the End Snap button is highlighted on the Snapping toolbar). When the pointer comes within the snapping tolerance of the existing line and you click to create the first vertex of the new line, it will be snapped to the existing line's endpoint. Since the start point of the new line is coincident with the end of the existing line, your electric lines are modeled as being connected.

  1. Click the Snapping menu on the Snapping toolbar and click Options.
  2. Type the desired number of pixels in the Tolerance box.
  3. Click OK.
