The New Drive user interface no longer contains the Create from template option as in Classic Drive.

However you can still get directly to a Create from template option via the File Menu in one of the Drive Apps.

Here’s How:

1. From within a Google Drive App (e.g. Doc, Sheet, Presentation, etc.).

2. Select File > New > From template…

This then routes you to the Templates Gallery for your Google Apps Domain where you can select a template

Alternatively you can go directly to the Templates Gallery via this link
