Hi,
Here is a possible way, with splines on two orthogonal planes to define 3D edge to sweep.
A few hints:
- you need to add the external fillets at the pipes junctions before the shell command, in order to get smooth edges inside the pipes
- the order of the fillets 01 and 02 is important, as well not including tangent edges for fillet 02. I started with a small radius for fillet 02 because otherwise it fails before disabling tangent edges
- I applied a 0.99 scaling factor to the center pipe to get a better looking result at the junction of the 4 pipes
Hope it helps.
