TS16 survey secret trick to create line on site part 1

How do we create line on site when we do survey, as build or as lay. When survey the points you create a line straight on site and later on it's ready when you open the file on your computer.
instrument went out of level and could not record the 3rd point which I show at part 2.
I hope you enjoy and save time when using it.
