Unlike sketches, projected curves (Sketch-sketch;sketch-surface) remain visible at all times, unless manually hidden. Is there a check box that will hide these curves in realtime? It is a pain while moving quickly to need to dig through the feature tree and manually hide each curve that I don't need.
I can understand why this has not been an issue for most engineers, but as an industrial designer, complex surfacing requires extensive use of projected curves. It can get quite confusing.
