Thank you for your response. I always appreciate guys at itoo's timely response ever since we purchased the software! One of the best I ever experienced.
Now I looked at your sample and it does work finding the length of a section, but I cannot figure out how to connect back to the x size of nested RC object. As the length is found using arithmetic, I cannot find a way to wire the parameter back (no key frames?).
For the solid doors, there are only 2 size(width) variations so I made 2 separate RC object and put them through condition node so RC put correct one in place, but for me it is not really elegant solution.
Also there is a glass door type which width varies between 880 mm to 1000 mm which I would like to incorporate as well. Because the size is not really fixed, I cannot simply make no. of RC objects to be nested.
I encountered one more issue. Following one of the tutorials, I managed to wire parameter of Z sizes of nested RC object (doors) and partition (main RC object). After saving the style to library and loading from there, the wired connection seems to got lost between the main RC object and nested RC object and I can no longer manage the Z size parameter in one place.
As we are always dealing with awful lot of partitions of various types, it would save us a huge amount of time if we can save them as style library.
I have attached a file, it would be great if you can have a look.
