I am using Fill Pattern to duplicate tubes inside a Heat Exchanger, but I am now trying to add twist to the pipes.

All tubes are patterned based on the central tube, which is swept around a Helix. Of course, the makes the central tube perfectly straight but surely the other pipes should have a twist as the move outwards from the centre?

I have tried both the pattern features and pattern bodies options but neither give twist to the patterned tubes.

Can anyone help? Model attached.

Regards,

Jon
