# File Saving

## Exporting

If your file contains multiple design alternatives or other working models, we recommend that you export your current design to a separate file. This way you know exactly which objects will in your exploration. 

* Select masses that you want to use in your exploration.
* Use the `Export` command to export to another Rhino 3dm file.

## File Size

Currently we only only files that are under 100mb to be processed. If your file is larger than that, or if you want to speed up the processing speed, you can use the `save small` option.
