Hi I've been trying to enclose three nodes (instead of two) by just adding another one at the end of the line but it doesnt work. Do any of you know how to do that? thx This one woud enclose nodes A and B but write a funny "C" beside: \ncbox[nodesep=.5cm,boxsize=.6,linearc=.2,linestyle=dashed]{A}{B}{C}
