Just a word of warning. A lot of these websites produce Archicad objects that are converted from other formats so can have many polygons and be much less efficient than proper Archicad GDL objects. This can bloat your file and slow it down. We tend to use as close as possible one of the built in objects and where we need to generate views of specific areas we use the actual objects on a different layer. It keeps the file size down.
