Change in line weight at intersections?

I’m in the middle of an elevation drawing and I’ve noticed that ever place where I have lines intersecting that the lines get thicker right around the meeting point. But the client wants a clean drawing without the additional weight. Is there a way to turn this off or is this something that I’m just seeing on screen and it will disappear when I make a pdf?

Try un-checking endpoints in the style window.


Thanks! I knew I forgot something.
