I drew a part (in the context of a top-down assembly) with a few sub-parts, features.

I want to move the sketch plane of one of the features and try to use the "edit sketch plane" option.

For that I inserted a new plane, but I can not choose it.

The new plane is a 3D sketch, but I don't need it that way, I only need a plane which I can choose to move the old sketch to.
