Load family directly to document

[Anonymous]

It is possible to load family directly to the current document without first saving it to a file. Looking at the api for loadFamilies and it only takes in a filename as a parameter. I'm working a plugin that allows only authenticated users to download and load families. I don't want these users distributing the families to other revit users without them first authenticating.

I have heard folks talk about web delivery or even embedding the families into the Resource of the application like icons, but once you have loaded them into a model, you won't be able to control them from there.

Hello,

As mentionned in the comment above, I don't think you can keep the property of families in Revit (unlike other softwares like PDMS). Indeed each time you import a family symbol in a document Revit makes a local copy in your Document of this symbol. And this symbol can not be protected.

Many architects tried and none succeeded. 

One friend of mine created a blueprint in all families, ie a hidden parameter that can not be modified except by code (Revit plugin). So that you can check a file of another architect to check if the young architect that he hired from you has taken your Families. But still, I don't think you will go far with this (juridically).
