Good afternoon, My friends
I use the lasso tool to select two process nodes, and how to get the link information between two nodes and two nodes. I hope these selected process nodes can be kept in horizontal or vertical middle.

I’m not sure if I understand your question. Regarding the sequence flow connecting two flow nodes do you want to get its properties? What do you mean by kept in horizontal or vertical middle?
