Looks as if you have a detailed fascia with lines merging into each other... Also, why not just used the objects cut and uncut linetype settings? Why GOs?
I don know about merging fascias (quite new to AC), but it happens to all UNCUT lines. I would like to be able to switch between different graphic styles via G.O. rather than lines per object.
I just want something very basic in architectural representation, which is to differentiate between cut and view lines.
