Sketch 1 is showing a blue line for me. it needs a dim to constrain it in the vertical direction
Sketch 7 has a horizontal construction line with white endpoints. Those either need to be made coincident to another line, or the line needs a dim to define it's length.
strange. I really did not see the blue line… However, now both „problems are fixed“ took me a long time, but I want to do it right, as I am new to this world of tools and did no sketching ever before…
