Are true circular multipipe open ends possible?

Trying to set up a design workflow for fabrication where straight cylindrical parts are combined with multipipe connectors (possibly 3D printed) but it seems that the open ends of multipipes aren’t true circles?

Also not clear that multipipe can be used in a way to ensure surface continuity where the cylindrical ends meet multipipe ends. Attached .gh file shows the problem quite clearly…

Any help appreciated!

SubD ends cannot be exactly circular ([WISH] SubD second degree or changing degree of a SubD? - #6 by dalelear)

However, you can get arbitrarily close as you increase the subdivision level, so it’s possible to make them circular for practical purposes. Here’s a way:

(though looking at this now, I notice that although they become circular, the radius changes - I’ll see if there’s a way to prevent this)

Thanks very much Daniel. SubD and what it does ‘locally’ is a bit of a learning curve for people with a background with ‘engineering’ CAD softwares such as e.g. SolidWorks. But I’m getting the hang of it - with help!
