If you want to duplicate models in Keyshot in the same work space, all you need to do is right click the model in the project tree, and click on duplicate. This will lay another copy of the model in the work space, but it is laid directly on top of your original. Right click your model and select move object you now have the ability to move the model left right and up and down or rotate the model. by moving the model in any direction will revel the other model. Hope this is of so help.
