I try to set horizontal constraints on the two lines in the sketch that form the top and bottom of a rectangle. The option is offered on selection, but pressing the button yields no results.
In general i find i often struggle to add constraints, especially when objects already have incidental constraints sich a an given start point. I then can’t set eg length and horizontal/vertical. I can usually work around this by creating free lines, constrain them, and drag them. But that’s cumbersome. fan-holder.shapr (1.0 MB)
