Pipe Orientation

Hi,

I’m trying to create the joints to my structure (similar to the image above). However, I can’t seem to create the “slimmer” parts inserted in the pipes so that they are connected in the same manner.

Tried many ways to change the direction/ orientation yet nothing seems to change as the UVhexa.gh (272.8 KB)
coordinates of the pipes isn’t arranged in the same way ( I suppose). Is there any way to fix this?

As far as I can tell, it might be because of the line direction
