Beam Finishes

How can i create Finishes for beams?
i found this video but he didn’t share the script and the file

This link should help you get started: Paint Material Surface

i tried it but it is fake layer , we cannot calculate the quantities forit , just we can see it as color and this script didn’t generate physical object as finishes

Can you show what you tried? Give a little more info on what you’re after? The rvt and dyn would be a must.

that script just create a fake box around walls as you can see it in yellow color
but i need a script like this one in this video please check this videos
i need script as create finishing from room schedules for exterior Columns and interior Beams
