I have found an obvious defect during the work with "Use Annot. Scale for Single Line Fittings". They work only at the floor plan. On 3d views, even they don't work at sections. In Russia as a part of the project documentation on engineering systems demand an axonometry. In Revit it can't be drawn and some are content with an isometry. Because of the fact that "Scale for Single Line Fittings" doesn't work to issue documentation extremely difficult. I ask to eliminate this defect.
