i've tried that. i went into the MVO dialog, selected 3D renders and then went all the way down to the bottom under miscellaneous settings for library objects and deselected the "opening line in 3D" for windows doors and SK. made sure my 3D view MOV is set to 3D render and the opening lines are still showing. is there another step?
that was it. very counter intuitive and a bit confusing. create MVO for the two options, then set each object opening lines to override MVO or not, and then set the object detail level by MVO or not. I hope i remember this.
