GetLinkDocument() broken in 2020?

[Yien_Chao]

hi,

this command works well for all version, except Revit 2020.

.GetLinkDocument()

https://www.revitapidocs.com/2020/6f81c365-15d9-06b8-48ef-df84914fec60.htm

anyone experienced the same?

I have not had any issues with this and have it in several locations.

using (FilteredElementCollector rvtLinks = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_RvtLinks).OfClass(typeof(RevitLinkType)))
            {
                if (rvtLinks.ToElements().Count > 0)
                {
                    foreach (RevitLinkType rvtLink in rvtLinks.ToElements())
                    {
                        if (rvtLink.GetLinkedFileStatus() == LinkedFileStatus.Loaded)
                        {
                            RevitLinkInstance link = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_RvtLinks).OfClass(typeof(RevitLinkInstance)).Where(x => x.GetTypeId() == rvtLink.Id).First() as RevitLinkInstance;
                            dtLinks.Rows.Add(rvtLink.Name, link.GetLinkDocument());
                        }
                    }
                }
            }

thank you for your reply.

i will do some more tests

[Yien_Chao]

problem is i've tried to get document from many links (like 9-10), some works and some don't.

they are all loaded and all the worksets are open.

i will look further (im in Python by the way)

Hi,

Are any of the links from BIM360?, from Revit 2019 they need to be retrieved differently.

no its all on the server.

it still works fine in 2018, 2019, but somehow not perfectly in 2020.

Is it always the same link(s) that cause the issue? Do you have the exception error it throws when it doesn't work? 

[Yien_Chao]

yes always the same. i think a find my mistake! the GetDocument() was part of another code, which is use to retrieve the project base point of all links. So all this time it wasn't the getdocument but the issue was at the BuiltInCategory.OST_ProjectBasePoint .

I change it to basePoints = FilteredElementCollector(doc).OfClass(BasePoint).ToElements() and all works.

sorry for the misinterpretation

thank you for all your feedback!
