Hi, Please help me to sort this issue. 

I have created a vector using the above code. by createmark nodes 1 'by cylinder' option is selecting nodes of wrong component. Vector is created using two nodes shown in the figure by red arrow.

puts 'The selected node: $nids and Closest node: $cln'
puts 'the nodes are $cnd'
