Snapping tolerance

Snapping tolerance is the distance Edit Plugin uses to search for the closest vertex you are trying to connect to when you set a new vertex or move an existing vertex. 

If you aren’t within the snapping tolerance, Edit Plugin will leave the vertex where you release the mouse button, instead of snapping it to an existing vertex. 

The snapping tolerance setting affects this tools: Create Point, Create Line and Create Polygon.
  1. The tolerance is defined in pixels.
  2. The advantage of pixels is that the snap tolerance doesn’t have to be changed after zoom operations. 
So be sure to mark the checkbox for those layers that you need to snap to.
