I'd like to know how to list the only displayed all types elements in the floor plan. "Display" means it is within level range of the "Floor Plan Cut Plane Settings" dialog. I have to list only displayed element of all types on the floor plan, likes a selection by Ctrl-A. I tried ACAPI_Element_GetElemList using filterBits, but it seems to be displayed with the API_StoryVisibility type parameter of each element instead of the "Floor Plan Cut Plane Settings" dialog. For example, It is possible to check the level for all element, but it needs a lot of code to check different fields for each element.
