Calculation Method

The next sections contain a short overview of the principles that have been followed in the calculations for different types of structural members.

The calculations of weight and center of gravity are done in two steps.

1. A preliminary WCOG value is calculated for each component when the planar or curved panel is stored. This simple calculation does neither consider excess, shrinkage or compensation for plates nor does it consider end cuts, notches, cutouts or holes for profiles.

2. When the component is released for production, using ppanparts or cpanparts, a new exact calculation is made. This is done both with and without consideration of excess and shrinkage.

Both sets of WCOG values are stored in the planar panel, curved plate or shell stiffener object.
