Align cross sections of sweeps to surface

[kp1 (Kp)]

Hi
I have been struggling to create sweeps for timber lattice of a ceiling design. I keep failing to make the cross sections of these sweeps align to normal of the reference/base surface.

I know there have been a lot of discussion about ‘box pipes’ on this forum but I have not found solution to my problem yet.

Timber lattice on surface

Hello I am trying to make timber lattice on complex surface. THis is how it looks like with Box pipes.: [image] How to do rectangular sweeps along the ‘pipe’ rails that would be oriented perpendicularly to the surface? They are supposed to be think sections of timber. I tried everything!!! [image] diagrid.gh (120.4 KB)
