- Open the
Application menu and choose Open 
Open From Vault. - If you're not logged in to a Vault provider, you're asked to log in via the Vault Log In dialog. Fill out the form and then click OK.
- Use the Open File From Vault dialog to browse the vault and choose a MAX file to open.
- At this point, one of two things happens:
- If the file is available for checkout, a dialog opens letting you know that the file is under version control and asking you if you want to check it out before making edits. Click Yes.
- If another user has the file checked out, a dialog opens notifying you of this and telling you that you won't be able to save edits. Click OK to open the file in read-only mode. If you attempt to save this file, a dialog appears notifying you that the scene file is read-only and will not be overwritten.
- If you attempt to open a different file or use the New or Reset command while the file is checked out, a dialog appears asking if you want to check the files back in. Enter a comment, if appropriate, and then click OK to check the file in.
Alternatively, if you just want to create a new version on the provider, turn on Keep Checked Out and then click OK. A new version will be created, but the file will still be checked out to you.
