complex cylinder help
![aaron_wildman](https://cad.onshape.com/images/placeholder-user.png)
I'm pretty new to CAD and Onshape in particular. Can somebody tell me the best approach to draft this clarinet section? draft 3 separate complex cylinders - bore, inner cylinder, and outer - (via lofting) and merge them all together somehow? I cannot otherwise imagine how to make a hole that is this complex. Thanks for any input.
note: section 2 of the bore is not a straight cone taper, it is cone with rounded edges. The taper is gentle on the right side of section 2, but becomes more pronounced towards the exit on the left.

Because the bore is rotationally symmetric, you can sketch a half-profile of the bore from the side and then just revolve to create the shape you want. here is an example:

If you make the rest of the clarinet first, you can even sketch and then use the "Remove" option in "Revolve" to make a cut instead of a new part.
