@upadhye.vinay , just want to clarify 2 things
What you mean by 'on every plugin call'.
Do you want to:
- 1.1/ create this list at every document opening and then use it during the session with this document?
OR (and I would guess this is your goal)
- 1.2/ create the list the first time a document is open and reuse it in between session?
What you mean by 'list of the 3D model property':
2.1 List of categories/properties names? or
2.2 List of all properties with their values. I will cover
NOTE: Below I cover only:
- the case of .NWD files and consider them readonly. .NWF support user categories/properties and are inherently read/write so an approach different than what I described below is required.
- the case 2.1
In both cases 1.1 and 1.2, you will need to keep as a field of your plugin something like this
public class CategoryDetails
{
public string mName;
public List<string> mPropertiesNames;
}
private List<CategoryDetails> mCategoriesDetails;
NOTE:
- if you use lists, like above, you can build it ordered which will come handy
- alternatively you can use Dictionaries if you want to be able to do quick check for an existing category/property
- you can combine both List/Dictionary/HashSet, depending on your exact use cases
In case 1.1/ you build this at document opening and use it during the session.
In case 1.2/ you store this in a dedicated file, format up to you, JSON, XML, .INI, .csv, saved in the same folder as the .NWD with a name based on the .NWD file name, ex: "Xxx.nwd.categories.json".
When a document is open, you check if such file exists:
- if yes, just load it, done.
- else find all categories/properties names and create said file.
Hope this covers at least in part your question 😉
