Hi,
We want to align the diagram nodes based on a primary selection.Currently we are using Diagram.Selection.Items.FirstOrDefault() as the primary item and aligning the other nodes with reference to this primary node.But the problem is we want the first selected node to be considered as primary.But if we take the first item from the Diagram.Selection.Items,its changing randomly.Means we are not able to get the primary selection.Is that any way to do this?

Thanks,.
