Salut, je n'ai pas regardé la vidéo. Je suis parti sur un sketch général qui décrit l'envergure et l'angle de l'aile. Ce qui permet de caler les deux profils extrêmes. (attachement) Ainsi que deux sketchs de motifs qui décrivent les positions des rainures et évidement. Ensuite pour les sections, la ...

In Surface WB, you can use this tool for a quick result.

How to force it to follow your profile? I don't understand your question, surfaces follow by them self. How to force it to be tangent to the other surfaces? The profiles for the gordons are children of the interpolate curves. And cut with the split feature (partWB), so they are tangent. But gordons...

La fonction join curves de curves WB, le fait. Mas il faudrait voir le fichier pour comprendre le problème...

A part si le modèle est destiné à l'impression 3D, il est complètement inutile de modéliser un filet sur la CAO.

sauf:
- apprendre à le faire (pas inutile de comprendre le principe)
- la beauté de la chose (autant esthétique que poétique)

OK, i didn't understand the purpose of your start parts. I've tried to build the transition surface by using a "bridge" (red) to give some thickness, otherwise the surfaces are too twisted. you can move the sketch to adjust the shape. Check out my file. ;) But the twist between two blades is too hig...

I'm not sure to understand the drawing very well, but you can start like this: Choose the main axle of the object. Here can the Z axle. Then draw a first sketch to make the cylinder. Sketch will be on XY plane. You need to know the two diameters to constraint the circles. Select pad to extrude the m...

Strange shapes your design! So, I slightly modified the sketch to not have blend curves crossing them self. The workflow is as that: Make faces using ruled surface (carry out nice surfaces), or if you have a lot of edges you must to use the filling feature (select second degree to get stretched surf...

Reversed option could help you. Isn't it?
