you can break a link and make a line/curve local in a sketch but you cannot edit it
which makes the break link command hardly useful for any serious design work.
I really need to have the ability to access the edit points other wise I could just copy and paste
lines cuvres between sketches and forget the project tool.
Obviously I am talking about flat sketches not projected onto a 3d surface because here you would
need a fit curve command to match the fit points cvs onto the surface.
not sure how this is different to the way how Fusion calculates the curve projection at the moment.
