Re: Thickness of a shell / extrude a shell

I would like to expand the shell to a solid at the same value in all directions and then be able to do operation such as fillets or other on the part. Be careful with the wording. What you created in your other topic - a link would have been appropriate - is already a solid. A shell is something wi...

John_Doe a également ouvert un sujet dans le forum anglais: https://forum.freecadweb.org/viewtopic.php?f=3&t=62199. Une preuve que le forum français n'a vraiment pas le niveau. Va falloir se mettre à jour. On pourrait apprendre des pages en anglais. Ceux qui postent là-bas sont assurément meill...

Re: Projeter une esquisse sur une surface complexe

Je suis littéralement en train de m'arracher les cheveux, j'ai essayé deux fonctions différentes, des positionnements différents et rien ne marche ça s'enroule toujours autour de la pièce. et ce n'est pas ce que tu cherches? si tu plaque un motif sur une surface courbe, il va "s'enrouler"...

Re: How to correctly map a sketch on a curved surface ?

The typical workflow would not include any mapping. In this example I made two bodies and us a Boolean operation: I tried with a boolean operation and id did not went well. Yet, I've given you two examples, both working, one with a Boolean operation. Maybe I don't understand what it is you seek to ...

Re: How to correctly map a sketch on a curved surface ?

Sketch has still 40 degrees of freedom (DOF). Modeling only one quarter makes things simpler. Instead of of 20 elements you have only 8, instead of 27 constraints plus 40 DOF you have only 17 plus 8 DOF: SnipScreenshot-730c59.png This is how the simplified Sketch001 could look like:SnipScreenshot-c...
