So this is a strange question that I'm not quite sure to go about asking. Basically on our revit drawings anytime a wall joins with an existing demising wall it shows the new wall cutting into the existing wall by about an inch. I attached a picture of whats happening. My boss does not like the look of this, but I don't even know where to begin with changing it. You cannot even select the lines in the demising wall with the lineweight tool. Can anything be done about this or is this just a revit quirk?
