Closed Curve: ID:<ID>, <3D>, <is planar/circle> on photos used <p1> unused <p2>.
• <ID> is the ID number of the Curve object
• <3D> indicates if the curve has a valid computed 3D position and shape.
• <is a circle> appears if the closed curve is set to "circle" (which means the closed curve is projected onto the best fit plane and then fit to a circle). A closed curve can be set to a circle by checking the "circle" checkbox in the curve's properties. A circle is planar by definition so the status bar will not indicate that the closed curve is also planar. “is a circle” will not appear in the status bar if the closed curve has not been set to "circle". If the curve is planar but not a circle then this says “is planar”.
• <p1> is the list of photographs the Curve’s mark appears on.
• <p2> is the list of unused photographs the Curve’s mark appears on.
