 * : Manufacturer when known
 * : Manufacturer part number
 * : Description of the component
 * : Material when known


 * : Defines the shape of the fin. At the moment, only Trapezoidal fins are supported.
 * : The fin height.
 * : The distance from the front of the fin root to the front of the fin tip along the x axis. This may be negative. Setting this value will cause the Sweep Angle to be adjusted.
 * : The angle of the front of the fin, with a vertical front being 0 degrees. This may be negative. Setting this value will cause the Sweep Length to be adjusted.
 * : The cross section shape of the fin at the root, see Options
 * : The distance between the fin leading and trailing edges at the root
 * : Maximum thickness at the root of the fin
 * : Expresses the Fin Root Length 1 and Fin Root Length 2 properties as a percentage of the Fin Root Chord
 * : Usage depends on the Fin Root Cross Section and will apply to a taper length or similar, see Options
 * : Usage depends on the Fin Root Cross Section and will apply to a taper length or similar when multiple values are required, see Options
 * : The cross section shape of the fin at the tip, see Options
 * : The distance between the fin leading and trailing edges at the tip
 * : Maximum thickness at the tip of the fin
 * : Expresses the Fin Tip Length 1 and Fin Tip Length 2 properties as a percentage of the Fin Tip Chord
 * : Usage depends on the Fin Tip Cross Section and will apply to a taper length or similar, see Options
 * : Usage depends on the Fin Tip Cross Section and will apply to a taper length or similar when multiple values are required, see Options
 * : True when a tab for Through the Wall fins is required, see Options
 * : Distance from the front of the fin to the front of the TTW tab
 * : Length of the TTW tab
 * : Height of the TTW tab
 * : Thickness of the TTW tab
