How to "fillet" cyllinders in a truss?

Hi all,

I have a truss consisting of cyllindrical rods. The nodes are currently sharp corners where the cyllinders impinge. I want to smooth out these corner. So for example, I have an equilateral triangle. The edges are made up of cyllinders. There are sphere of radius equal to the cyllinder radius at the corners, so the exterior corners are smooth. I would like to smooth out the interior corners.

Basically i want to do a fillet, but on cyllinders instead of lines.

Any help is greatly appreciated.

Thanks,

Adam
