I am designing a bending jig for some wire-frame eyeglasses. I start with the nose-bridge, which is just a straight length of .040 wire about 1/2" long. Th free end of this length is a mirror image of the circle sketched at the origin/Csys. Elementary. Now I want the next segment to extend generally along the axis of the first, but also angle about 40-degrees in the 2nd of the 3 orthographic dimensions (per the original Csys) and 30-degrees in the remaining dimension. Getting the 40-degree bend is obvious. I do not know how to establish a second Csys at the free end of the first segment, if that is a preferred approach. I do not see how I can get my sketching references (it wants the usual minimum of 2) once I have bumbled into establishing a datum plane which is at the aforementioned obliqueness to my original Csys. Anyone who does plastic injection mold design with Pro-e is no doubt quickly closing this window in favor of something more challenging. I don't even know how I got my plane established (it's too hard to even tell if it really is correct) and I have no references to begin the actual sketch. Obviously I need help in this. I'm stuck with 2000i2, but I am sure they carried over the basics of auxilliary datum construction into current releases, so I will be deleriously happy if someone here can kick me in the right direction. Thx.
