What happens if somebody edits the same feature in QGIS?

This version of QGIS does not track if somebody else is editing the same feature at the same time as you are. The last person to save its edits wins.

Do you have to digitize second polygon in QGIS?

If you already have one polygon, it is possible with this option to digitize the second one such that both intersect, and QGIS then cuts the second polygon to the boundary of the existing one. The advantage is that you don’t have to digitize all vertices of the common boundary.

How do you select a vertex in a feature in QGIS?

With activating the Node Tool on a feature, QGIS opens the Vertex Editor panel listing all the vertices of the feature with their x, y (z, m if applicable) coordinates and r (for the radius, in case of circular geometry). Simply select a row in the table does select the corresponding vertex in the map canvas, and vice versa.

How do you snap to a feature in QGIS?

Now in your QGIS settings you will need to decide how you wish to SNAP to features. Choose the Settings > Options menu and then the Digitising Tab.
