I'm reworking a part in an assembly. Due to changes in the design, the former part that the sketch was linked to does no longer exist. Now I have a sketch that tells me that it's "Parent of the plane has been supressed or modeled away" which makes sense, since the part is no longer there. However I would like to keep this sketch, as many other features down the line depend on it's geometry, and remodeling the sketch will probably break all these parts. Is there a way to assign a new datum plane to this sketch? Hopefully without breaking anything down the line.
