Hi to all of you , ProE users!! I'm trying to create a drafted offset , into a sfere that must appear like a step in the body. I'd try to sketch the curve that will be the reference for the drafted offest , but i don't know how to apply that to the sfere in both sides. Someone can help me ??? Any suggest??? Tanks in advance!! Regards Bye
Dimples, anyone? Copy offset your spherical surface (inward, outward, doesn't matter). Create your curve geometry on a plane outside the sphere then offset/wrap your curves onto the surfaces, bigger outside, smaller inside for negative draft; bigger inside, smaller outside for positive draft. Put points on these "on surface" curves as attachments (or use breaks, vertices in existing curves) for cross curves. Use these curves for creating boundary blend surfaces, essentially style surfaces. Merge the surfaces. Alternatively, create a Style feature with, essentially, these same curves and end point tangency set to Surface Curvature, because you will create the intial curves as 'on surface'.
