Hi Jacob, yes that kind of thing is possible to do in a Sketchup plugin. There are a few different ways to implement it. I think the best way depends on your workflow. But I have some ideas. I could write a very simple version for you. Maybe something that just export all the surface area of different materials used in a model. Then it would be easy to use a color coding system in Sketchup. Then run the plugin and it could output the area associated with each color. Then you could take that into a spreadsheet.
I’m not good with formatting text output in Ruby. But I could get the data for sure, and then you would just need to plug it into a spreadsheet manually (well, copy and paste).
So PM or email me or something. I’ll see if I can get a quick and dirty version of the script up and running.
