[Qgis-user] An issue splitting a shape

[Bernhard Ströbl]

Hi Andrea,

I have seen that the geometry checker marks pseudo nodes (no idea why). 
anyways I can use the split _features_ tool (the left hand scissors tool 
in the advanced digitizing toolbar) on the layer.
This is QGIS 2.14.0 on Ubuntu 14.04 64 bit
