| − | Besides layer based snapping options the General tab in menu
| + | |
| − | Settings -> mActionOptionsProject Properties...
| + | |
| − | also provides some topological functionalities.
| + | |
| − | In the Digitizing option group you can Enable topological editing and/or activate
| + | |
| − | Avoid intersections of new polygons.

| − | <P>
| + | |
| − | The option Enable topological editing is for editing and maintaining
| + | |
| − | common boundaries in polygon mosaics. QGIS "detects" a shared boundary in
| + | |
| − | a polygon mosaic and you only have to move the vertex once and QGIS will take
| + | |
| − | care about updating the other boundary.

| − | <h4>Avoid intersections of new polygons</h4>

| + | |
| − | The second topological option called Avoid intersections of new polygons
| + | |
| − | avoids overlaps in polygon mosaics. It is for quicker digitizing of adjacent polygons.
| + | |
| − | If you already have one polygon, it is possible with this option to digitise the second
| + | |
| − | one such that both intersect and qgis then cuts the second polygon to the common boundary.
| + | |
| − | The advantage is that users don't have to digitize all vertices of the common boundary.
