How can 2 truncated cones with different drafting directions be combined tangentially?

[Woifi]

Hello,
I have two truncated cones with the same starting point. The cones need to be substracted from a body for a screw hole. Due to different tooling directions of the part and the one it should be attached to, they have a different drafting direction.
If I just create the two cones an edge is created (see picture).
I wanted to ask you what would be the easiest/cleanest way to get a smooth hole.
(I am using NX2212)

Thank you!

They can't, you will need to figure out how to add material for them to join to. A few thousandths will work.

How do you plan on manufacturing this part? The process used might limit your options.

The easy way to clean it up would be to apply an edge blend to your current model. Alternately, you could build a smooth transition surface between the 2 and trim them back. Neither of which would be feasible if this feature is going to be made with a spot drill type operation.

cannot say that i understand the question.
Are these cones side by side as in the image ? and the issue is that there will be an edge where cone meets cone ?

Try using a sweep, you can use different "rails" and you can sweep your circle along these two rails. Imagine the top rail at your draft, and the second rail 180 deg opposite and at sketched at your different draft.

If its a screw hole? can you just make it a slot that's slightly oversized and punch it normal to surface?
