Hi there,
For an export plugin I need to get only architectural elements, when i get all elements, i don't know how to filter them to get only architectural elements (building elements, everything i need to compute Global Cost and Life Cycle Cost). I know there is a FilteredElementCollector (got it on buildingcoder blog), but i don't know how to modify this to get only building elements, i don't want elements like views, sunlight, renders, and everything i don't need.
