Making sketch from other parts of an assembly visible/in-visible is used in a much different way than in this case.
The major use is to make a sketch from a part visible so that it can be used to create assembly level features with reference to other parts in the assembly, that cannot be made in...
In the PathFinder tree, right click the part or occurrence and select. From the menu Select Show/Hide component. In the dialog check OFF sketches.
Hopefully this should work.
