Material reference

[Anonymous]

Hi reviteers,

There are 7 types ofExternalFileReferenceTypes.

I am using this code to retrieve references in a revit project:

ICollection<ElementId> externalReferences = transData.GetAllExternalFileReferenceIds();

I can retrieve:

ExternalFileReferenceType.AssemblyCodeTable

ExternalFileReferenceType.CADLink

ExternalFileReferenceType.RevitLink

ExternalFileReferenceType.KeynoteTable

but there is also a

ExternalFileReferenceType.Material

But the code above never gets materials ??

What is this setting for ? Is it supposed to retrieve the rendermaterials ? And if so, why doesn't the code above retrieve them ??

Is the a way to get a list of missing materials and fix the links ?

The materials are not included as ExternalFileReferences after Revit2012. So you cannot get anything by ExternalFileReferenceType.Material.

okay, but is there any other way to get to the material locations ?

I made a tool to fix missing links and it works perfect for keynotes, assembly codes ect. but not for custom loaded materials.

As far as I know, there is no API support for getting customized material location.

But if you want to get the installed material location, you can use the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Autodesk\ADSKAssetLibrary\2017" and the Key Name "LibraryPaths" to retrieval the installed material library location.

Hope that can help you.
