Hi again Barry,

Thank you so much for your explanation and the attached file too!

Am I correct that to point the ends downwards, you did "Show pts", selected the ones and the tip and then dragged them down in the z axis?

Many thanks!
Gunter

“””””” Also, I'd like the pointed ends to bend downward slightly (in the z axis). Could you explain how I can do this please?””””

Use Flow

Before you bollean and fillet the parts together, do a curve-curve flow.

Hi Gunter,
Yes I just moved curve points.
Cheers
Barry
