Get Materials of Multi-layer components from current selected Wall

mcbabo — Wed, 07 Dec 2022 18:59:56 GMT

I want to extract the materials of a wall I have currently selected

I only know that I get the selected elements with this code (i guess)

GS::Array<API_Neig> walls; GSErrCode err = ACAPI_Selection_Get(nullptr, &walls, false, true, API_InsidePartially);

Thanks for your code, but could you please explain the functions of every line. I am very new to the API, so I don't understand all of it.
