Hi OSTexo,

Is the attached file what you want, or does it have the intersections you're talking about? I made this by doing Construct > Offset with Mode = Through Point. The selected object was the rail that already had the blend in it. The point that I picked was on one of the straight stubs that hadn't been blended yet.

But, making the matrix of pipes straight like with Extrude and then doing curve to curve flow like Michael suggested should also work pretty well for keeping clearance between the pipes. The only problem I've had with that approach is that for really long skinny things like wires the cross section can end up out-of-round.
