On peut voir ces lignes en choisissant l'affichage "ligne cachées". Cela affecte la grosseur du fichier FCSTD si je ne me goure.

Freecad turned it on itself while I was handling part design. Not my fault, I swear. that's the reason I was stuck.

chrisb win! I never saw this option before. thanks

Why I can't get some external geometry from Sketch002 to Sketch003? :roll: ...

Salut,
dans assembly2, je ne sais pas si tu as bien mis cette option à la partie fixe?

Pour faire le coude, on peut créer un chemin sur un plan passant par une génératrice du conduit. Ensuite on peut faire le sweep avec la face (flèche rouge) et le sketch004.
Bonne continuation

When Gorgon surface works better a Sweep.
While a Sweep or a PipeShell gives BopAlgo GeomAbs_C0 error, Gordon doesn't carrying out that and allow to do an 3D Offset.
And surfaces are pretty identical.

direction of the trim006 should be z=1 isn't it? and picked point seems wrong.

For a path's sweep, this can avoid to define an other sketch.

same thing with a flange.
