Pro members and above can duplicate models that they own. This can be useful for displaying different versions of the same model, such as, for example, different texture sets or annotations and descriptions in different languages.
To duplicate a model, click the Edit Properties button on your model page.
Once there, you'll find the Duplicate button on the left-side of the page, or you can find the Duplicate option after clicking the gear icon on your model's thumbnail (see both below).
A copy of the model will be added to your account in Draft mode, with " - duplicated version" added to its title. The model copy will have all the same metadata, properties, and 3D Settings as the original model. However, stats like views and likes will be set to zero. It will not be in any collections and statuses like Staff Pick will not be preserved.
When you publish the copy, it will be at the top of your recent models and your followers will be notified of a new model.
