Hi,

In a -complex enough - part, I am using a surface1 and surface2, twice extruded with sketch1 and 2.

If I want to change sketch2 to sketch3, for using the surface2, how can I do that ?

Of course, I would keep the surface2 name, and all constructions done with surface2, behind the scene.

A joined file to illustrate the problem, but without any sequence behind the scene, using surface2.
