Multipipe issue

I am having an issue with multipipe- I am sure it is a pretty easy fix, but I have done some looking around and and not sure how to fix it. File attached.

I want a smooth finish, and there are some straight very thin parts that I don’t want and I am not sure how to get rid of.

Thanks in advance!

the typology might look like this - still can be optimized … a first fast go:

as tom mentioned, build it in three pieces, then delete faces / stitch edges to get what you want-

@DanielPiker may be able to chime in on why that joint is failing. It may simply exceed the number of curves MP can handle at one time to make a joint.

Ahh this makes sense! Thank you!

Thank you!
