I tried to draw polygons in QGIS 1.7.0 and somehow I can't find or failed to find the "Snapping" option.
I'm used to ArcGIS 10.0 where you have some snapping options, like placing points of polygons at points/edges/shapes/etc., see image below.
Is this also possible with QGIS? And if yes, how to activate it?
I've tried to figure out all the editing options, but couldn't find any snapping or similar.
Answer
In Settings / Options / Digitizing, you can define the distance radius in pixel or map units to snap to other points.
And in Settings / Snapping options you can choose which layers can be used for snapping.
The only thing that does not work is snapping to the points of a line or polygon you are just creating.
Software version: QGIS 2.18.20
