I love the smell of new question in the morning.
I searched the forum but couldn't find any related topic about sharing values between RC objects. It's kinda master style but as much as I understand, master style only duplicates the RC object right? Everything same but the base spline. Is there any way to read some data from another RC object?
i.e. I have a style which creates frame system with a lot of options, user values etc. I want to create another RC style with decoratives which easily fits into the frame system, on the same spline. I may ask the user same questions again but matching all required values manually is a painstaking process. Also leads to errors. (especially when you have many copies) If RC can read some defined values from master style, it is possible to create more versatile and lightweight styles.
Actually it's sounds like Macro! You define inputs/outputs. Is it possible to access this values?
