Hey Virtual Lab-
I was curious about this myself, and I must say that I am dissapointed with the final outcome but.... From what I understand, you place one object, then place use the marker add button, ( Ibelieve it is under trqansform) , Then place another object, and another marker... Now go to the tool palette and use the "multi-marker tool" to place the collection of objects. Now you can go into edit mode, and individually move objects till you are satisfied with the general placement. Now you must convert them into a polymesh3d...urrgh! This allows you to edit the meshes, but not the entire objects anymore. If this works let me know... there is a Zscript that comes with Zbrsuh that will walk you through this. If you find a better way please..... let me know!!!
