It would be useful if one to many and many to one relationships could be represented by links. So a node could have a labeled link emanating from it which splits and goes to several nodes. You can see examples in the maps created by IHMC Cmap Tools at their website http://cmap.ihmc.us/ .

I would rather use VUE than Cmap Tools as it is more aesthetically pleasing and has some facilities that are lacking in Cmap Tools.

I found out how to do this!!!!!!

Not a perfect solution but it looks good.

You have an intermediate node, one with a smaller font and zero thickness border and a background colour the same as the sheet background. It doesn't matter how you format this node but it should be different to the normal nodes.

Join all the 'many' nodes to this node and then join it to the destination.

Paul,

Was just going to suggest the workaround you already found, glad you found a solution.

I noticed - merely by accident - that you can connect a link to a link. All you do is select the link tool and start drawing your new link at any point on some other link. VUE always makes that connection at the center of the original link and the added links do stay connected when you move the original link. I do not know how this is handled internally - whether all the child nodes are considered connected to the parent node or the intermediary link, but it works on the screen.

I've seen this and used this feature, but it is as far as I can tell graphical only - the connection report does not show a connection across a link connected to another link. An easy way to see this is to use the Extended Selection tool in the Exploration Tools. You'll notice that the extended connections will not bridge across such links. It will connect across an intermediate empty node, but that node counts as one more degree of distance from the chosen node, so it's still not quite right.
