Hello Deon You can use the function Avoid Intersection while digitizing. In this way you avoid overlap - but not gaps. Read more about this issue in the usermanual

I have two boundary vector layers, the one exist of polygons of all the provinces and the other of all the districts. The district boundaries must be aligned with the provincial boundaries. Since there is so much errors that needs alignment and rectification I was wondering if there isn’t an easier way as to snap to the boundaries without to drag each vertex which is very time consuming. Is there perhaps a way where the whole identified segments/vertex of the districts can be aligned easier to the provincial boundaries. Regards Deon Pretorius
