So I follow the directions and a couple of things
No auto constraints are created in the way the tutorial describes
The lines are not linked (even when I start the next line highlight the end point of a previous line yellow)
I was able to manually select both end points and select the "Coincident constraint". Though I can't imagine that is what everyone does all the time. I assume this is a simple newbie kind of issue and your guidance would be appreciated.
Had a squiz at the tutorial you have linked to. Yes indeed, the base shape before being padded is all single lines (and an arc).
To draw a new line joined to the last one, FreeCAD Sketcher relies on the user getting the mouse pointer over the end of the previous line where the dot turns yellow and then clicking to start the new line. Very tedious initially, but with practice you become very proficient at finding the end of the previous line.
Another way as mentioned in the tutorial text is to draw the new line adjacent to the previous one, then 'capture' the two ends and place a coincident constraint on the pair of adjacent line ends. You report being able to successfully select line end pairs and create the coincident constraint.
As for Auto constraints - In the task panel confirm the Auto Constraints checkbox is ticked. (I've found previously that even when it is ticked sometimes it does not appear to work consistently, so if it isn't working - cycle the tick off and re-tick the Auto Constraint checkbox) As you draw a line vertically (or horizontally) the line is auto-constrained to the vertical or horizontal. When you finish the line, a vertical or horizontal constraint will be automatically created in the list of constraints. As the line is being drawn when the line is rotated through the vertical or the horizontal, the auto constraint should show adjacent to the line.
Similarly, when drawing a new line from the previous one (yellow dot when mouse pointer is on the first line end) a coincident constraint will be automatically created upon 2nd line completion.
Believe me, it does get easier (I started drafting in pen and ink in the 70's), sketching is very powerful as you learn more features. I tend to draw all sketcher lines separate but adjacent of any length and in a rough direction, not coincident or horizontal/vertical. I then select the individual lines to create any orthogonality (vertical/horizontal) and angular constraints, then followed by end pairs to create coincident constraints along with length constraints.
Hope this helps.
