LEparagliding

This program is used to design parachutes and parasails with circular geometry. The current version (0.2 20200417) still is very primitive and does not allow, many options. Nevertheless, it is usable for designing the shape of the gores, and calculate the length of the main lines. You can continue the design editing the dxf output file.

The following improvements will be adding the seam edges. Dividing gores in sectors, and adding different types of windows and vents. More complex designs of lines, with ramifications. Dome shape defined in base on profiles defined by the user. Possibly add other geometries, such as square.

Of course, the program operates at the typical cryptic "Fortran style" of the Laboratory.
