Getting the phase map

[cwaluga]

In Revit 2019 there is a nice function RevitLinkType.GetPhaseMap() which allows us to obtain the information on which phase maps to which in a linked document scenario. Is there any way to obtain this information in older versions?

Document link = linkElem.GetLinkDocument();

Dictionary<ElementId, ElementId> PhaseTable = new Dictionary<ElementId, ElementId>();
PhaseTable = link.GetPhaseMapping(doc);

I don't seem to have the GetPhaseMapping method available in any version of Revit (see also here). Are you sure that this is not a non-standard extension method? If you have something that works I would appreciate if you could explain how you obtain the map. The only thing that comes to my mind is making assumptions like "Phase in host is equally named as in link", which may not hold true in any case.

Yes sorry, it's an extension method I used to ask the user to "define" the mapping.

Haha, happens to all of us! Nevertheless, thanks for the effort. I guess if you went that far to ask the user, you did also not find a good solution.
