Thank you both! That's exactly what happened: I had clicked on one of the arrowheads by accident, which is a new one on me. Much appreciated!

A strange thing came up while I was mid-drafting. Suddenly, any arc or line I try to draw now contains a large indicator arrow as I'm trying to draw it. For a lot of arcs, it's bigger than the arc I'm trying to draw and so I can't see my arc at all while I'm trying to draw. These arrowheads remain after the arc or line is drawn. Does anyone know how to get rid of these or what weird setting I accidentally clicked?
