I am quite fond of the fact that I have not to add constraints but can adjust length and angle in a sketch.
This is quite convenient for better drafting.
drawing a line 1.5 mm and then 90 degree from an edge can help making some parallel offset lines by hand.
But then what makes the engine very hard is the auto join and trim of curves.
I would rather prefer the way how Fusion does it which giving the user access to surfaces found inside a closed shape without trimming the lines/curves.
