I have been trying to make three arcs which each touch the others at one point so that they form a complete perimeter around a space. I have put datum points at each of the points where they touch and at the centres of the arcs. Unfortunately when I use the Endpoint & centre arc tool the points I place do not automatically go to the datum points when my mouse hovers near them, because of this Creo never regonizes that they join at a particualr point and I am then unable to extrude the shape. How can I define points that the arc points will "snap" to when the mouse hovers close?
