Arrows on pivot line of walls

[mukster]

Hit a button somewhere and now all my center lines have arrowheads on them. How do I get rid of them?

[JeffH · Accepted solution]

Go to view, then On-Screen View options

It will be the Wall & Beams Reference Line.  Simply click it off

Do note that those arrows are purely symbolic and do not show up anywhere else.
