LE paragliding lep-2.90 version: This version is the result of working intensively in the source code of LEparagliding :) There is a lot of invisible work in subroutines and code improvement.
Improvements:
- Section 26 allows the vents part to be attached automatically to the extrados or intrados at will. Already explained in version 2.85.
- Section 21 Joncs definition (nylon rods), now fully functional.
Now it is possible to define type 1 rods, which are the most used. A rod on the edge of attack with small deflections at both ends, which are completely controllable in position and depth of deflection, with 8 parameters. The program calculates the rods and shapes of the pockets, which are also fully controllable in widths, with 4 parameters. It is possible to define different rods for each cell, individually or by groups.
Of course, sections 26 and 21, save a lot of drawing work with CAD, and now the paraglider is almost finished from the program.
- Section 22 Nose mylars, now fully functional.
- Extension of the DXF-2D plans to an array 4 rows x of 7 columns (28 plans). Plan 1-7 used for rods. New plan 4-7 includes general text notes for constructor.
The work of the division in colors, is only with a section of partial help (marks of reference). And the division in 3D panels on the leading edge and the improvement of the skin tension module, are the following works. Following my drawings, it is now possible to add one or two cuts in 3D, but it is a lot of work if the paraglider has many cells. That's why we will automate!
Version 2.87 includes as example the paraglider BHL5-Bi 31 m2 "etude version", still working. The program now generates completely finished plans, ready to build and fly!
Version GUI Graphical User Interface, It is also evolving, thanks to a Swiss programmer... But for now, you need to try to understand my  drawings and cryptic explanations and write the parameters directly into the text file!

January 2019. Working with the source code of the program, in several sections (21 joncs, 26 vents union, 29 3D-shaping, and 31 new skin tension in panels), and rewriting the code that draws the panels, with new subroutines . A new generation of wings is on the way.
lep-2.87 Section 21 joncs, and section 26. "Glue vents" now is fully functional :)
