Title: Setting direction on connectors
Post by: R Glenn Walker on March 06, 2024, 10:54:54 am

I have written a simple script that creates composition links between an element and any child elements. It works except that when I try to set the direction, I don't get the effect for which I am looking to achieve. I want "Source -> Destination". But it always sets it to "Destination -> Source". I

         var theElement as EA.Element;
         theElement = Repository.GetTreeSelectedObject();
         
         elements = new Enumerator(theElement.Elements);
         while (!elements.atEnd()) {
            var element as EA.Element;
            element = elements.item();
            connector = element.Connectors.AddNew("Part Of","composedOf");
            connector.SupplierId = theElement.ElementID;
            connector.Direction = "Source -> Destination";
                                 // Assuming need update here so that the supplier end is filled in properly.
            connector. Update();
                                // this works fine. Aggregation is showing properly.
            connector.SupplierEnd.Aggregation = 2;
            connector.Update();
            elements.moveNext();
         }

Aggregation links are subtle (you will find quite a number of ancient posts by Paolo here). Just use source and target the opposite way you tried.

Have tried both ways. But, no joy. The aggregation property is set properly. At this point, I am left with manually selecting and changing the direction of each link.

I recently had the same issue.

It worked when I set the ConnectorEnd.Navigable property
