The beginning of the figure is shown by the start dot/circle. The initial line is dashed so we know the airplane is beginning this figure with a negative AoA, and since every figure begins on a horizontal line, the airplane must therefore be inverted. The first ‘corner’ is a push up to a 45° line. We know it’s a 45° line and not 30° or some other angle because straight lines can only be horizontal, 45°, and vertical. The inverted 45° line is now followed by an inside (positive AoA) 3/4 loop which terminates in another 45° line up. This time, however, the line style is solid, so we know the airplane is upright (positive AoA). That positive line is next followed by another 3/4 loop, but this time drawn as a dashed line. That tells us the loop is outside, or negative. The outside 3/4 loop ends in yet another inverted 45° line. Finally, the figure ends, as all figures do, on a horizontal line, though this one is dashed, or inverted. The vertical hash line tells us the figure is over at that point.

As odd as some of the figures in Families 7 and 8 first appear, you now know all the Aresti notations necessary to figure out exactly what the airplane should be doing at any point in any figure.
Up to this point we’ve been talking about the Aresti notations necessary to understand the flight path and attitude the airplane will follow when flying any of the basic figures found in Families 1 through 8. If you’ve been following along in your Aresti Aerobatic Catalogue, you have likely noticed that most figures have additional curved-line symbols located on the figure, this Family 8 figure being one example:
Much earlier we said that Family 9 consists of the rotational elements: aileron rolls, snap rolls, and spins, and that they must complement one of the basic figures. But it turns out you can’t just sprinkle rolls and spins on a figure anywhere you want. Once again, the Catalogue is our builder’s guide to exactly what we can and cannot do with the rotational elements on any given figure.
Looking at Figure 12 below, the first symbol we see, besides the figure itself, is a curved line passing completely through the horizontal entry line. This is the “optional roll” symbol and it simply means that when it comes time to construct a flyable figure, the designer of that figure has the option to: (1) do nothing and simply let the airplane enter the 5/8th loop without any rolling; or (2) has the option of putting one or two rolls at that location which in their total extent of rotation do not change the character of the line after the roll or rolls are complete.
