How to correctly map a sketch on a curved surface ?
Hello everyone,
I am here to ask you a question related to the mapping of a sketch on a curved surface.
I managed to unify the support of the sketch with the curves workbench, and to map the sketch on the surface. However, I want the sketch to be centered on the surface and i want it only on the exterior of the surface, i don't want that the sketch wrap itself around the surface, and that's exactly what's happening.
So I would like you people to explain me how to do in aim to cure this issue.
Thanks a lot

You should link all the answers you get in french forum : https://forum.freecadweb.org/viewtopic.php?f=12&t=62090

And that's what this (great) function is supposed to do. Perhaps you rather want Part->Create projection on surface; which does basically what papyblaise suggested.

Re: How to correctly map a sketch on a curved surface ?
Your file is still a mess:
- Links go out of allowed scope, don't put Sketch nor Sketch001 into a body. - Sketches not cleaned as suggested by Shalmeneser
- Where does the BaseFeature come from?
Please help the helpers by reducing the complexity of the models as far as possible.

Well, i tried this "great" function and the result was messy, so i do not really know how to use it, hence my post.

This example is just an example, I am working on another file that I cannot share here. On my other project i cleaned everything by using symetries.chrisb wrote: ↑Tue Sep 14, 2021 8:20 am Your file is still a mess:

The base feature is from the join curves operation that i did in aim to obtain a single solid without edges.chrisb wrote: ↑Tue Sep 14, 2021 8:20 am Your file is still a mess:

Re: How to correctly map a sketch on a curved surface ?
I appreciate it, if you don't upload the full model with all its probably irrelevant details. Every step further which simplifys the example is even more welcome. Boil it down to the bare minimum.

Here we are,
I put symetries on both sketches, and both sketches are not on a body, now, what should I do ?
I also tried the other function as suggested, i have the nearly same result, the sketch is wrapped around the surface.
