Im trying to make a part that had an angled end to it and each end is a different radius and ive been trying to figure out what to do I've looked up videos looked on here and nothing to help me so far this is probably a very easy problem to fix for someone who knows what they're doing so hopefully I can get some help on this ive attached a few pictures as well thanks. The diameter of the big circle is .308" and small one is .205" and the feature is 1.450" long

Watch this video for details on how to create the relation with trajpar.

Looks like you may be close. You do not show your tree, so I don't know how you created what you have. Create a boundary blend between the two ends, merge the surfaces and solidify.

There is always more to learn.

so ive got half of it to work but when I go to the other side it doesn't work again I'm not sure if I'm doing something wrong I assume I am since I can't get the whole thing to connect any advice? Thank you. Surface Connection 4.JPG

You do not need a second direction for the boundary blend. When selecting the chains for the first direction hold Shift to add the second side of the circle.

See Attached 7.0 model.

See the enclosed Creo 7 model. Variable section sweep handles this nicely and is quite robust. There is a relation in the sweep section that defines the rate of taper from .308 to .205 diameter. Sketch 1 is used as the trajectory and the sweep section is constrained to the trajectory to get the desired geometry.
