Select only visible objects! Delete all objects hidden inside other objects!
If you are working with object heavy CAD models you probably know that often 90% of the objects are hidden internal components of the rig. Stuff you usually don't need or want. Object count that make 3dsMax crawl.
This script lets you either select what is visible or hidden from the current view - or let you scan the whole scene.
It's a very efficient way to clean up your scenes with a high accuracy!
