find position of Revit link

[Anonymous]

I am trying to find the position of Linked Revit models in my Project. The locationPoint gives null and I couldnot

find the position.

    FilteredElementCollector collector = new FilteredElementCollector(myDoc);//
                collector.OfClass(typeof(Instance)).OfCategory(BuiltInCategory.OST_RvtLinks);//RevitLinkType
   

    foreach (Element elLink in collector)
                {
                    Instance ins = elLink as Instance;

                    RevitLinkType linkType = myDoc.GetElement(ins.GetTypeId()) as RevitLinkType;
                    LocationPoint pn = linkType.Location as LocationPoint;

                if (null != pn)
                {
                    TaskDialog.Show("rvt", "location " + pn.Point.X + "     " + pn.Point.Y + "    " + pn.Point.Z);
                }

            }

Select your link in RevitLookup and explore its properties.

Does it have a Location property?

If so, you can access that through the API.

I just noticed your identical question on StackOverflow and provided another answer there which may help further:

Look at The Building Coder discussion of Determining Host Document Location of a Linked Element:

`RevitLinkInstance` is derived from the `Instance` class, the base class for all instance objects. It provides the methods `GetTransform`, to retrieve the transform of the instance, and `GetTotalTransform` that includes the true north transform as well.
