This Full HD video is showing how to quickly disassemble huge object to layers, and then to separate objects in specified folder.
It's using TrueArt's Modeling Pack
http://modelingpack.trueart.eu
Surfaces To Layers tool is splitting object to layers, each surface to separate layer.
Parts To Layers tool is splitting object to layers, each part to separate layer.
TrueCenter is used to interactively center or rest object on ground.
Save Layers To Folder is finally saving each layer with name to folder at once. Layer must have a name, which is used as file name. Surfaces To Layers and Parts To Layers are setting layer name automatically.
