This is an issue I've experienced before with swept cuts, but never with swept bosses.

I'm attempting to make pie-cut tubing for this intake piping. To sum up the issue as best as I can with words, the boss does not follow the path the way I expected it to. See screenshots below.

As you can see, my path is not normal to the circular sketch on the left hand side there. I tried attempting the sweep with a circular profile at the other end, but ended up with the same result at the end: the sweep does not end normal to the end of the path.

I'd like to resolve this without modifying the configuration of the path if possible. Any suggestions? Thanks guys!
