Ok, so I'm pretty frustrated. I want to change the thickness and color of tagged leader lines. NOT text leader lines. That's easy. I went into object styles and changed the annotation objects to my color and thickness preference. Now, this apparently works for section and 3D views but NOT plan view. This is driving me crazy.
What's even crazier is that I got the duct tag leaders to be the way I want it but not the tagged mechanical equipment. I went into additional settings to played around with the line weights and arrowheads, but nothing. Anyone have any bright ideas?
