Check out the Extensions Warehouse, I cant remember the extensions name itself. BUT the authors name is Chris Fullmer, there is a authors column to select from. I am ALL MOST positive it is free and it allows you to select the item. It needs to be a component or a group if I can remember. Then you can click and drop it. As many times or any random order or plane. Great for plants or trees and I thought you could constrain or plot points say if you are dropping lights or parking meters in a Mall parking lot. He has a short video that shows what it actually does before you install it to see if it fits your needs. Check it out…Peace…
Just checked $10.00 dollars but that is still very reasonable if you are working commercially.
