EnSight offers several options for duplicating parts. As discussed above, copying (see Copy Parts) is shallow and exists only visually on the client. Merging (see Merge Parts) allows the combining of one or more parts into one, created (dependent), deep, child part. Right-clicking an existing model part and choosing Load Part (reloading a model part) does create an independent new part from scratch. Extracting a part makes a deep copy of just the visual components of the part. And now finally, cloning which makes a deep copy of the part including its attributes.
