Thanks, ! Got it ! aero and hydrodynamic bodies design => goal !
Gordon will be my new friend, and i will don't cling to the seagull's wings

Here we go !

/!\ Github repository available /!\ i've just created a Github repository to simplify work on Template / Implementation method / test : https://github.com/soaring-community/freecad-pattern i've uploaded previous files posted by hammax and GlouGlou, it's under GPL3, set by default because need a lice...

Thank you ! i didn't be aware of this workbench ! Serious work, with a good development plan ! But as i understand (with my little knowledge, please correct me) : There are 3 workbench dealing with surface / nurbs... : - Silk - Nurbs - Curves I will simplify but my feeling is : Silk work on sort of ...

whoa, so cool, thanks ! i've just played with compbound object (didn't use before) and try to do some basics gordon surface test with sketch lines as path, but freecad go in infinite loop... i need to test again with approximation curve, behind there are DWire objects, can you tell me how do you con...

Ok, Gordon surface is a huge step forward and seems to have important fix from november. is someone can update the seagull file with an exemple on how to use it to create the wing (currently two method used : sweep and sweep2rail) : https://forum.freecadweb.org/download/file.php?id=73731 I understan...

Done, and i think will be better for testing curvesWB

Thank you, i've updated links index of this thread with these two lines :

2nd observation : before the final design workflow step (approximation), we've got the "sweep 2 rails" step. Question 1 : what is the color code used for drawing point ? Is there some information regarding color ? Question 2 : It seems that naturally some foil where design with plots, but there is o...

So, Freecad is back ! My first observation is regarding the Trailing edge.

with standard Loft/Sweep, we can see some broken / "rasterisation" on the edge, with "sweep by 2 rail method", it's ok.
it was for me a limitation for wing design... good news !
