Hi, Thanks,

but i need do that in the background, that's why i need to make a plugin, but i don't know how to get values from a family or behavior programmatically. (Javascript SDK)

For example, get X for each solid objects.

(Im gonna make a json with that values, and i want to make it easy for users)
