In the attached image, the left is my 1st floor RCP, which looks the way I want. The right is my 2nd floor RCP, in which I cannot get the door jambs (orange lines) to turn off. Cut Planes are set identically in the two dwgs. I thought the Display Configuration settings were identical in the 2 dwgs, but clearly they're not. Can you advise?
Took a quick look - the components that are displaying in your 2nd floor plan are Wall Below Cut Plane components. Not sure why they display in that drawing and not on the 1st floor plan, though. There are an awful lot of style-level overrides, which multiplies the opportunities for display settings to vary, although I did not see anything obvious tonight.
