I have a linked file and tried to override lineweight of some ducts by either host view override and custom view settings of the linked files...It seems I am not able to use the lineweight settings of my hosting file. Revit is using the lineweight settings inside the linked file! That's odd to me! Is this a known glitch or am I setting something wrong??? I also tried in the new 2013 and behavious is the same. I have my own settings and it would be redicolous to change linked files lineweigght settings from consultants everytime!!!!
