I would love to be able to update wall material on all my walls at once without also resetting gable, header height etc. Maybe this could be a global parameter or when multiple walls are selected, and materials are changed that only that parameter be updated.
Example, I have house that is basically a box, but because of roof and floor levels I have 15 exterior walls. Cycling through them for the fourth time to change material I am imaging a more efficient approach.
I understand that each wall is essentially a dynamic component, and asking them communicate is tricky. Thanks to Rubysketch for the hardworking innovation!
