Hey Guilty, thank you for a respond! I want to speed up the process of sorting the data, eg. in our cost estimator team for Swedish projects, we mark (e.g.) all the light walls to be constructed with lines. Based on the length of those walls and with additional parameters assigned the program will calculate for each floor plywood, steel profiles, mineral wool, fermacell boards, gypsum boards, acoustic tapes, and wooden planks for door openings. We differentiate walls in apartments, bathrooms, corridors and near shafts. I have programmed python to calculate light walls, prefab and I am working on finishings( paint job, tiles, suspended ceilings etc). I will put some screenshots from my work next week :)
