possible to Pick elements of a linked Revit model and return its parameter?

[glenncai]

Try to pick a beam from a linked Revit model.

I have try this:

Reference refe = uidoc.Selection.PickObject(ObjectType.LinkedElement,"Pick a Object"); this part works

but:
Element e =doc.GetElement(refe.ElementId); element name is the link model not the beam I picked
Element e =doc.GetElement(refe.LinkedElementId); error: Object reference not set to and instance of an object.

also try a solution from Joe Ye:

still no luck

I tab to select the linked element and use IDs of Selection but no Id return. is it possible to get the element parameters from a link? any suggestions? Thanks

Hi,

the linked element resides in the linked document, not in the main document.

You say:

"Element e =doc.GetElement(refe.ElementId); element name is the link model not the beam I picked"

In fact, e is a RevitLinkInstance.

So you find the linked document this way:

Document linkedDoc = (e as RevitLinkInstance).GetLinkDocument();

And the linked element:

Element eLinked =linkedDoc.GetElement(refe.LinkedElementId);
