Hi Michael,
i will give the new version a try, and I will also try that tip with the exact lofting.
I may use some time to do that, because the project now entered a new stage
(preproduction), and I am certain that I will face new tasks very soon.
Best regards
Heiner
(and thanks again for your awesome support!)

Hi Heiner, I was able to track down why there were unjoined edges in your object there when using the default Loft settings - it was due to Loft not using a tight enough fitting tolerance in some cases.

I've got it fixed up for the next v3 beta so that it will be fixed.

Thanks, - Michael
