Modifying "Keywords" parameter of a Material

Anonymous — Mon, 06 May 2019 13:13:35 GMT

Hello,

I am trying to create an add-in which takes data from a Spreadsheet and creates materials in a Revit project. So far I can easily access every property of a Material or AppearanceAssetElement and edit them. All except one, which are the Keywords in the Identity tab (Descriptive Information). I've done research on the subject and I couldn't find any working examples of code. The Material class doesn't have any kind of property or Parameter for this kind of data.

I have no problems with setting the value of Keywords in Appearance asset for the material (I do it by accessing the "keyword" AssetPropertyString of the asset), but I haven't found a way to access the Keyword property of the Material. I am coding in Revit 2018.3, with updated Visual API, and the documentation did not provide any help on the issue.

Additionally, I have accessed the journal file, where I manually edited the Keywords value. It resulted in the following entry:

Jrn.Data "MaterialProperty"  _
        , "", "physmat_Keywords", 1 _
        , 0, "new, test"

So it seems like there is some kind of a property connected to the Material object, but I have no idea how to access it. Is it even possible to edit this property via RevitAPI?

Thank you!
