When laying down decks in areas of sloping framing, it is necessary that each different sloped area be assigned a distinct deck polygon. A separate deck polygon is required for each different plane.

If an individual deck polygon encompasses an area of framing that is sloping at multiple angles, the analysis in RAM Frame and RAM Concrete Analysis may be incorrect and the deck will display incorrectly in the 3D view (the deck will appear to float above or cut through the framing). Thus for layout types with sloping framing the Whole Floor command should not be used (unless the framing is monosloped), and multiple deck polygons will be required.
