The Union node will output the boolean union of two Vectron inputs (figure 1).

Bounds - Determines the bounds of the Vectron geometry.
Input 1 - The base Vectron object.
Input 2 - The Vectron object that will union Input 1.
Radius - Increases the intersection area, higher values will produce smoother results.
