I have never understood this, if I alter default line thickness to a thicker line, nothing changes on screen.
The lines are sometimes too thin to read, I could do with a means of thickening some layers, so that when zoomed out they show as lets say 4 pixels thick on screen, and whatever zoom one is at , they always display at 4 pixels on screen. I dont want to find that as I zoom in they get fatter and hide other objects etc !
Obviously their central line is stil the active part, I dont want snap mode snapping to their thick edge !
How is this done ?
