I need a simple tip for drawing line shapes in QGIS. I have multiple line shapes in my project that needs to be connected, so is there an option to join my already drawn line with the line that I'm drawing so they can have same connection point, but without zooming it to the max?

What you are looking for is doing a snapping operation, which is a very common task in a GIS software.

Simply, go to Settings >> Snapping Options... and set where to apply the snapping and a custom tolerance. For example:

enter image description here

In this way, when you will try to digitize a new point, QGIS will automatically snap it to the nearest vertex (from another layer) that is within the tolerance set.

If you need more advanced options (for example, enabling snapping only to specified layer, select Advanced from the Layer selection box).

    I prefer to use 10 pixel tolerance instead of any map units. – AndreJ Jul 3 '17 at 11:18
