Your results may vary, but something on the order In our smallĭigitizing project (working with the Alaska dataset), we define the Tolerance doesn’t have to be changed after zoom operations. The advantage of choosing pixels is that the snapping You can also define a default snapping tolerance andĪ search radius for vertex edits. You can select between ‘To vertex’, ‘To segment’ or ‘To vertex and segment’Īs default snap mode. A general, project-wide snapping tolerance can be defined by choosing.The snapping tolerance setting affects all tools that work with tolerance. Will leave the vertex where you release the mouse button, instead of snapping If you aren’t within the snapping tolerance, QGIS Vertex and/or segment you are trying to connect to when you set a new vertex or Snapping tolerance is the distance QGIS uses to search for the closest SpatiaLite, PostGIS, MSSQL Spatial and Oracle Spatial vector layers and tables.
