Hello all,

When digitizing with "avoid intersections" option turned on, QGIS should detect the layer type when creating new features.

Imagine that I draw a square. After that I draw a rectangle, that is wider than the polygon, but shorter in height than the square.

        |      |
    ----|      |-------
    |   |   A  |  B   |

If my layer type is MultiPolygon, QGIS should:

a) have a configuration to maintain it's multipolygon status and create only a single feature;
b) ask if we want to split that in multiple features;

If my layer is Polygon, QGIS should:

a) split that feature in two features, each of corresponding to one of the outer rings created.

Hello Jurgen,

I configured this bug to be of high priority because it cause massive problems with digitizing land-use features.

The users cannot, after some time digitizing, figure it out which polygons are multipart (on a single part layer) and some of the work can be lost in consequence of this.

This is just my two cents :D
