I have a range of electrical objects (+50), each time I make an addition I need to add a parameter manually. I wish there was a way to export that parameter or all parameters as an xml then import them into the next object along with it's values.
What you should do is create your own Subtype for your electrical objects. Parameters in this Subtype will appear in all child objects of the Subtype (in blue). If some of the parameters are not used in particle Objects, then they can be hidden and removed from parameter transfer.
