# 3D Model versions
**Simplio3D supports 3D model versions to easily update a configurator without adding or updating option blocks.**
When you are updating the 3D model inside a configurator there are 3 rules:
1. **Keep the same naming of the 3D model.** Do not add “V2”, “V3", etc. to the file name, because the system considers it to be a different model; it will automatically create a version number within the system.
2. **When selecting a new 3D model version.** When selecting a new 3D model version for the configurator, leave the old model version checked and check the new one, only in this way will all the model properties be transferred to the new model version.
Selecting new 3D model version
3. **Same 3D parts naming.** If the 3D parts do not have the same name as the old version of the model, the system will not transfer the properties to the parts of the new model.

If these rules are not kept, all options will not be linked to the new model and the configurator will no longer function properly.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.simplio3d.com/learning-the-app/products/add-3d-models/3d-model-versions.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
