Hi!

It would be awesome if there was a node in grasshopper where you can set different parameters for RC objects. For example the concrete cover, max rebar diameter and/or spacing etc. It would make the autodesign much more useful in grasshopper.

Best regards,  
Ture

Hi @Turez

Have you already tried the cfg input of the grasshopper component?

Creating a custom node is definitely on of our plan
