        <p fontName="Arial">1. Divide the roof symmetrically in 4 quarters and find areas and centroids in 3 projections;

2. The average slope measured perpendicular to the wind direction is calculated as the ratio of the frontal area in that direction to the square root of the sum of squares of areas in 2 other perpendicular projections. 

(For a plane this slope will be the "normal" slope as seen through a cross-section, but for a curved surface it will be less. It is the slope of a plane surface having the same footprint respectively in 3 projections as the curved roof surface, and can be interpreted as the average slope on that surface, as the wind will "see" it. The pressure coefficient corresponding to that slope should be selected, which will result in a decrease in the calculated pressure if that slope comes closer to 30 degrees than the slope of the main cross-section, or an increase if it becomes less than that. This method applied to the vertical direction can also allow the verification of the actual vertical slope for the rain &amp; roofing requirement;)

3. To eliminate the small differences between centroids found in 3 projections, each coordinate of the centroid in 3D is calculated from the weighted average of that coordinate in 2 directions.

4. Multiply the area in each projection with the wind pressure and the CPe for the average slope as seen from the direction of the wind, for each component of the wind force as per normalprocedure.</p>
